I still suggest getting a 3500+ socket 939 processor. And the MSI K8T800 Neo2. That mobo you have isnt the greatest.
And if you do that you can get two of these, have better performance out of you RAM, and save 50 bucks.
Also you can get XP pro, not home, for cheaper.
I bought this same product from this same seller a few weeks ago and its legit and cheaper too.
