I want to buy either Atlon II x4 640 or Athlon II x4 750K, but here is the catch:
My budget is kinda tight atm and i would like to avoid spending unnecessary money as much as possible.
I already have ASUS M4A77TD ((socket AM3) AMD770 chipset) motherboard and since both CPUs costs almost the same in my country - it bugs my mind that i should buy some mATX FM2 motherboard and use 750K instead of older 640 CPU, because that would be clearly wiser judging from the future perspective.
But i would like to avoid spending those 60$ for motherboard if possible
So my question would be:
1) If i buy athlon x4 640 (since i got mobo for it) will it bottleneck my HD 7750, while gaming with 1280x1024 19" monitor, using 4gb ram?
2) Roughly how much more performance i would get if i'd decide to buy 750k system instead of 640 (please estimate in % if possible)?
3) What the hell would you do in my situation? haha
