Hi i am currently looking to upgrade my GPU to something that will make a substantial difference in my PC performance while playing games, I currently use a SAPPHIRE Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 and I also use an Intel 3750k CPU and 600w PSU, and 8 gigs of DDR3 RAM.
Like i said i want to upgrade my GPU to something that will make a good amount of difference in performance i am looking the this card:
other link is not working, but based on the 2nd one yes you will feel the difference. but personally it is better to skip a generation before upgrading, saves money and makes the improvement (fps-wise) that much better
I could be wrong but your first link was to a 7870 model, however if you looking for a big upgrade then I would go to at least the 7950 and maybe even save up and get the 7970 (non gig ed). That would be a better and better jump in performance.
