A GTX 640 is faster. Neither is great for gaming though. A 500w power supply is good for any single card up to a GTX 670 as long as it's a decent power supply. Make and model? And budget for a graphics card?
what company cpu do u have and does it have a pci connector if not the best graphic card u can get would be a hd 7750
I agree.
The GT 640 is more in line with competing with a HD 6670, which is also low power consuming. I'd much rather go for the much more updated and more powerful 7750, which isn't all too expensive.
