so i assume a i5-4430 and gtx 750 ti will be good? maybe i should get a 660 later.
660 is a generation behind. If you want to push your machine to the next level, its best to save up your money and get a
REALLY REALLY good GPU to leave upgradability to 4K eventually. Say, the GTX 780 Ti, which is a $700 card. Why such a loving expensive card? ..Because the CPU isnt
nearly as important as the GPU for gaming, which is why for a truly great machine you pretty much need to dump half your budget on the GPU. I am serious about this. In this case for now, 300/2 = $150. a 750 Ti. You'd need an adequate PSU to run better GPUs, but that might only set you back $100 if you choose the right PSU, maybe even less.
And I do mean really really good; preferably getting a larger resolution monitor with that.
Though, you should wait, because the 800 series is around the corner.
