I've not kept up with hardware.

I need to buy a new cpu and my budget is $175 for the cpu. This is for the computer that I blew the power supply up in. Gaming machine mostly.

I'm debating between these two:
E8400 Wolfdale 3.0GHz 6MB
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115037

Q8400 Yorkfield 2.66GHz 4MB
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115057

I've already got a motherboard. I had sent a defective mobo from gigabyte and have the refurb in.
I also need a power supply if anyone can donate a decent one. I'll trade a rackmount case for it.

If you would consider used, which on a CPU I hope you would, you can pick up an E8400 for $95-$110. I bought one last month for my uncle's new PC for $100 shipped.

Q6600 is my recommended buy for a quad-core IF you get a G0 stepping chip. The B3 runs extremely hot and has little overclocking ability, but a G0 will pretty much guaranteed hit 3.4ghz with a good cooler and they sell for less than $150 fairly regularly.

No, I am not talking about eBay. Yes, if you are interested I'd be glad to help.

EDIT: Not sure how much you care about overclocking, but either stepping of that E8400 will likely get you to 4.0ghz with little effort, many of them do it with less than stock volts. It's a very good chip, but games like SupCom and I assume SupCom2 gain alot from a quad-core.

hardforum.com, troll for used items

saw a q6700 on craigslist for $150 a while back

See, you missed this on the HF

"Intel Q6600 SOLD

Code 2 Quad LGA775. Yes, it is a B3 revision and never overclocked. Includes the stock HSF.

Looking for $115 shipped."

Would also recommend the Q6600 and just would recommend a quad in general cause they are awesome.

you can pick up an E8400 for $95-$110

There's an E8400 for sale for $105 right now on Hardforum.
