my guess is you want a quad core with hyperthreading... an i7 920 may be a little old but its still a great cpu... it should cost less than a i5 2600... all in your probably looking at 400 minimum for motherboard cpu and ram... regardles of whether you choose a quad i5 or an older i7...
I thank you for your response on my ?. hyperthreeading is for sure what i need, I will find a i7 920 to buy but i still need a motherboard to accommodate the CPU at its fullest. What do you suggest here? My OS is ging to be win7 64 bit.
