mikerockett thanks for the quick suggestions, but I waited for about 2 hours and all the prices changed so quick. Should I just go for the 430w power supply(19 after rebate) or should i spend like 10 more dollars for the same psu but 600w?
For this pricerange i would (and did) buy a 5800k and ASRock FM2 mobo. I believe it was the best performance for my dollar. I am able to play World of Tanks at about 60 fps (med settings / selected settings off) and guild wars 2 (med - but i don't know fps - my son's game).
It's a good, entry level gaming machine for my son. It's able to overclock the CPU and GPU ... (will need a cooler - i went with CM 212).
This is sure to cause much disagreement.
I realize you don't want to overclock at this time. That's not a requirement with the 5800k, however - I believe it's nice to have and the ASRock Bios is extremly easy.
i3 will be fine too - I am thrifty and when faced with this problem i voted with my money - 5800k. It meets and exceeds my gaming goals for this machine.
Also, i believe in the next year or 2 new games will depend on more CPU cores. This may also help in your decision.
Good Luck !! I'm sure you will be happy with your new build.
