hiii i am going for a radeon 6670 ddr3 2gb (and about the 1gb ddr5 version i cant get it because im unable to find it on any shop in my area they just dont have it dont know why only this one i have found so thats why im going for it) i want to know what will be its performance when combined with a core2duo 2.8ghz and 2gb ddr2 ram (800mhz) i'll be playing on 1600x900 resolution. so what you guys think the performance this card would give on games like bf3,crysis,gta 4??
