The HD 5870 is more than double the overall performance of the HD 5770, a couple other cards to consider may be the HD 6790 and GTX 460 768MB.
GTS 450 -> HD 5770 -> GTX 550 Ti -> HD 6790 -> GTX 460 768MB -> HD 6850 = GTX 460 1GB
I might go for the 6790, either that or the 550 Ti.
In the next few weeks I might have a little bit more budget so I’ll wait and see as well.
Thanks for your help guys, I appreciate it, if I don’t get an increased budget I’ll choose between the 6790 or the 550 Ti, if I do get an increase in budget then I’ll post that here.
Sorry for the double post;
Just measured my current graphics card, it’s 17 centimetres in width and 20 millimetres high.
(Item Height: 20mm
Item Width: 17cm)
The 6790 is:
Item Height: 6 centimetres
Item Width: 25 centimetres
The 550Ti is:
Item Height: 40 millimetres
Item Width: 11.1 centimetres
The 550Ti would fit without a doubt, but I’m not sure about the 6790, it may be too big. I tried measuring inside my case and it might just fit, but I’m concerned whether it would clash with anything else.
Depends on how the inside of the case is setup, but also make sure there is enough room at the back of the card to plug in the 6pin PCI-e connector.
When I put the side of my case on, I have ~1mm clearanve between my sidefan and the top of my CPU cooler 
I suddenly see why people buy full ATX cases…but I never would, portability is an issue.
I’d go for it, especially since it comes with DXHR. Only 16 left right now though.
Fair enough, my case should be okay, to be safe I’m looking at cards that are roughly the same size anyway.
Lucky. Yeah, I agree with portability being an issue, hence why I want to stick with what I’ve got. Damn, I was away for the weekend, missed that offer. :fffuuu:
I’ve found this, a refurbished GTX 460noparse[/noparse], but it doesn’t come with the drivers or any cables and such (Not sure what cables are needed for.) But this is a good price, think it’s worth getting? Would anybody know the size of the 460? As you can tell I’m stumbling all over with these cards, seriously unsure of what to go with. 
Here is the NVIDIA page for the reference GTX 460, for non-reference designs you will have to consult the manufacturer’s website.
https://www.nvidia.com/object/product-geforce-gtx-460-us.html
Height: 4.376 inches (111 mm)
Length: 8.25 inches (210 mm)
The GTX 460 requires 2 6pin PCI-e power connectors, so you may need 2 converters if your PSU doesn’t have the required connectors.
Ah I believe I’ve only got 1 6pin PCI-e power connector, will have to double check that.
Sorry for making this thread really long since I’m pretty bad and deciding what to get, I’d just like to get the best for my computer for possibly £100. What other specs would you need aside from what I’ve listed in the OP to determine the best graphics card?
If I were you, I’d completely ignore the 400 series, go with the 500. It may be a tad more expensive, but it runs significantly cooler and my 560 destroys everything I’ve played on it.
550Ti is on my list, I’d just like an ATI card so that I can decide between the 550Ti and whatever ATI card is the best suggestion.
HD 6790 would be faster than the GTX 550 Ti or a HD 5770/6770 which is around the same performance level.
On a side note with the HD 6000 series, except for the rebranded cards like the HD 6770 and 6750, ATI has been completely removed and the GPU’s are now marketed as AMD.
Be careful-- when you were looking for very low-budget cards it was one thing, but if you start looking at the gtx 460 and other similar cards you need to make sure that your power supply can handle it. The gtx 4xx series was very power hungry and produced a lot of heat; the 5xx series is better but more expensive as it is a newer generation.
I would recommend a 550ti if you can find one at a discount, otherwise a 5770 (even though it performs worse; the 6790 is the 550ti’s performance competitor, but draws a LOT more power than either the 550ti or 5770, and isn’t as good of a value IMO). Both draw relatively little power, require only one PCI-E connector, and have good performance. The 550ti is better than the 5770, but either one would serve you very well.
Thanks for that, I appreciate it. How could I find out my power supply without actually examining it physically? Is there anyway of finding out using a program? I tried CPU-Z, but I’m not sure where to find the power supply.
If it helps, here’s the complete analysis of my computer using CPU-Z.
It’s either the 550Ti or the 5770, the 6790 draws too much power and seems too big for my computer, so to be on the safe side, it’s either the 550Ti or the 5770, and either one would benefit me well.
More than likely you’ll need to open your case and look at it physically. Shouldn’t be that big an issue, since you’re going to need to open your case to put the video card in there anyway.
Actually looking at the PSU will be the easiest way to find the specs.
If they are priced evenly then go with the GTX 550 Ti, otherwise just go with the better deal.
[i]Side note the HD 6790 actually uses slightly less power than the GTX 550 Ti, though reference design calls for 2 6pin PCI-e connectors, and it is about 10% faster, whereas the HD 5770 and the GTX 550 Ti performance difference falls in-between a margin of error.
As for the GTX 460, they run very cool and even at reference design they don’t come near breaking 80c, their power consumption in comparison to their competition is slightly higher, but more than acceptable.[/i]
It’s actually impossible to find your PC’s power supply wattage rating programmatically. You have to open it up and look inside. First, though, try looking at the back of your case; sometimes the wattage is printed on the back of the PSU, where it will show through the case. If you can’t find a wattage anywhere, find a serial number and google it.
Scratch what I said earlier-- the 6790 pulls less than the 550ti apparently, but not less than the 5770 (by a small margin). I don’t remember what site I was on when I made that last post but I assume I read the info incorrectly. It does require two 6-pin pci-e cables, but a molex-to-pci-e adapter would solve that issue as the power requirements are still reasonable.
The 5770 would be my budget choice though if I could find a good cheap unit. They were very popular, and plenty should be available used as people upgrade their components.
Thanks guys for your help, I’ve decided to go with the 5770. Since it’s a budget choice and enough to support what I play on my PC.
Sometime in the future I’ll have more money to pay for a higher end card.
Thanks for all your help and sorry for dragging this on to 3 pages.
However, if I do manage to earn a bit more money in the next 2 weeks I’ll go with the 550Ti.
