Countless hardware failures (likely to do with the mobo)! And now I have no choice but to do a major upgrade to the PC after 5 years. I will be keeping the 600W power supply, DVD drive and the WD Cavier Black 1TB HDD. Here is a list compiled by a netizen from another forum for me: Intel Core i5-3330 Ivy Bridge ASUS P8H77-M H77 Corsair Vengeance DDR3 1600MHz 8GB MSI GTX660Ti TWIN FROZR 3GB GDDR5 SSD Plextor 256GB M5S Series 2.5" SATA3 However, I read that the 192-bit memory bus would handicap a GTX660 Ti so it is not that better than the 256-bit 5850? If I kept it, is the 5850 good enough for an i5 CPU and not be a painful bottleneck? Please educate me.:infinity: P.S. I plan to play Battlefield 3 on 1920 x 1200, no AA, HQ.
