Hi all so i have
core 2 duo e6750 2.66 (stock)
2gb ram ddr2
365w max HP psu 100 ~ 240v
so i wanna buy new GPU and 2gb or 4gb more ram
so can u help me decide a decent gpu which can max out games like gta iv and upcoming gta five or mass effect 3 bf3 protype 2 assasins creed 3 under 1280x 1080 ( thats the max res my moniter can give )
i was thinking
HD 5670 1gb ddr5 shader v5.0
i have seen many videos in which HD 5670 has maxed out all new games
You can find the HD7750 for ~$100 these days. It is ~3X as fast as the HD5670 and uses just a little more power than the HD5670 too. Since your CPU is unlikely to be fast enough to keep the HD7750 busy, the HD7750 will likely end up using a lot less power and this may let you stretch your generic HP PSU's lifespan a little longer.
You have to be careful about which model you get. Some 7750s have DDR3 memory and you can find them NEW at around $80 and others have GDDR5 which provides about twice the RAM bandwidth and cost closer to $100 new.
With a GDDR5 HD7750, you can play most games with most eye candy enabled at 1920x1080p.
If you want to know how much these are worth used, eBay is your friend.
