I was wondering if theres anything I should watch out for when looking that dual and quad cores.
I remember I bought a p 4 2.40 years ago. After I got it I found out it was a "D" version which was the slowest. Seemed like a dirty trick to me. Are there things like that with the dual and quad? \
also if I go with the rig I picked above will it be considered a high end machine I can use for Gamming?
Hate to nitpic, but there never was a P4 2.4 "D", unless you mean a Celeron D 320, which runs at 2.4GHz. There were four socket 478 P4s offered at 2.4GHz: The 2.4A, with Northwood core and 400MHz fsb; the 2.4B, with Northwood core and 533fsb; the 2.4C, with Northwood core and 800MHz fsb; and finally, once again the 2.4A, this time a Prescott Core and 533fsb. Only the 2.4C offered HT.
As for your questions, everyone likes the GO stepping CPUs. Either motherboard will work, but you really don't have to spend that much money on a mobo just to game.
