Upgrading my computer, Best build price/performance?

Ive seen like 10 motherboards around my price range i just have no idea which one is the best for example: ASRock B75 Pro3-M or a Z68 Pro3 Gen3, i wont be getting the 660TI as i fear it will not fit in my case and im stretching my budget as it is. I will post the psu model tomorrow i know that its not some seasonic or OCZ psu but i remember it being rated 80+ silver or bronze which is around the same as brand psus.

I only checked one example for each, but a 660 and 660ti were the same length: 9.5" (24.1 cm). They appear to have the same power requirements as well. (Your 500W PSU should be adequate if it delivers at least 24A on the +12V line.)

You appear to be suffering from a case of upgrade fever. I don't know how long you'd have to wait to acquire funds to do a less constrained upgrade, but I'd recommend waiting.

As far as EVGA are concerned........both the 660 and 660 Ti both require 450watts. I compared the lowest end 660 vs the highest end 660 Ti and both recommend at least 450watts. Find a good online power supply calculator and plug in your components like your CPU, HDD, GPU, etc and see if your 500watt PSU is up to snuff.
