Hey guys, So as the title says I'm planning to buy a new graphics card. My current one is pretty outdated (1024MB ATI Radeon HD 4600 Series). I already have a new card in mind which fits my budget : ASUS GTX750TI-OC-2GD5 I just wanted to make sure that my computer is gonna be able to handle it, or if anyone maybe knows a better card in the same price range ? here are my specs : Operating System Windows Vista Home Premium 64-bit SP2 CPU Intel Core i7 920 @ 2.67GHz Bloomfield 45nm Technology RAM 12,0GB Triple-Channel DDR3 @ 533MHz (7-7-7-19) Motherboard Acer FX58M (CPU 1) My psu should be 450watts. Anyone think this could give problems ? thanks in advance.
