Right now i have a i7-860 2.8GHZ, 8 GB RAM, ATI HD 5850 1 gb (motherboard is intel DP55WB). I want to upgrade it. So far as i gathered to change the processor i need to change the motherboard, so i was thinking more of a changing the graphics card. Friends suggested GTX560TI 1280MB/GDDR5 GV-N560448-13I GIGA-BYTE cause it's awsum they said or go for ATI HD 7950.
I'd like to play most games on high settings (resolution is 1920*1080 etc). Wll the 7950 be overkill and the rest will bottleneck it or is the GTX560ti 448 better solution?
