Hello! I'm having a sweet job over summer and thinking about spending about $300 on a new graphics card. My current computer is P5B Deluxe Q6600 at 3 GHz 4 GB RAM 620 W Corsair PSU GTX 275 I'm thinking about 560 Ti, or perhaps HD7870/7850. Will it make a difference worth spending the money on, or will the GPU be severely bottlenecked by another component? The idea is to play new titles like Mass Effect 3 at highest detail and both AA and AF enabled at my monitor's 1280/1024 native resolution, with a minimum of 60 fps. Always. Thank you so very much for your input! Masklin
