Optimal Graphics card for a poor CPU

7750, make sure your PSU is 300W (or above) and have 1 PCI-E x16 slot.

But I think you'd better build a whole new PC.

if u have a PSU of 400w buy a HD 7750 it is best vieo card for this range.....

I really dont have money for a good enough processor.But could it make any difference if i overclocked it? And i want to buy a 2GB RAM stick so i can have 3GB of RAM.
With all that complete i would then have these specs:
CPU: Intel dual core e2180 @ 2.0 GHz (overclocked if you recommend)
RAM: 1x 1GB, 1x 2GB.
PSU: 450W
GPU: radeon 7750 (maybe i could splash 170$ for a better one? what do you thnk)

I honestly, think 7750 would be a bit too much. Remember that the e2180 is the super old pentium dual core. I personally think even a 6670 is going to be slightly bottlenecked. So my opinion is save the money and buy the 6670 tops or you can try the 6570 since really, that's all you should be running.

Passmark rates your cpu as 880 points, that's LOWER than the celeron ultra low 17w laptop sandy bridge processor.
Even if you overclock it to like 2.5-3ghz, you'll just barely beat the sandy bridge celeron...

Passmark isn't a good benchmark software that you can judge it on. Celeron Sandy Bridge processors aren't that bad. I don't think that they would bottleneck a 6850 really. So, yes OC it to ~3GHz and have fun with the 7750.

No, I don't think your $170 would be that useful, because 7750 is the max. I understand that just with a little bit of an increase with $170, you can get a 1GB 7850, but your processor will give it a bottleneck. So, a 7750  .

As I told you before in my first post, I think you'd better upgrade the motherboard + cpu + ram + case ((yes not the whole thing, sorry for that!) if it doesn't support ATX motherboard, although MicroATX is fine).

The best reason to get a 7750 in your case is due to the low power use for the performance. You pretty much never have to upgrade a power supply to use it.

Since it's well in your budget, it would be a good pick, even if/when you upgrade the CPU, it will hold it's own. Instead of the RAM, I'd look into upgrading the CPU to something in the 2.5 gig + range.

Celeron Sandy Bridge for desktop isn't bad. The mobile 17w ultra low on the other hand...

While I agree passmark isn't the best, it does give you an idea of how well it runs. At least when compared to other processors aroudn the same level.

Anyways, I'd only get the 7750 if you are going to get a new computer relatively soon. If not, get a cheaper gfx card and upgrade later.

Hi faris - For $130 you can get hd7770, it is a low power draw, but not as low as 7750,
but what is your psu(wats/amps on 12v rail)?

Get a new desktop, no discussion.

Incorrect - varis is orig poster and is looking for a GPU, already stated he does not have
enough $ for a new processor, so it follows a new desktop is not part of the original
topic/request.
