There is no such thing as a 3.6ghz cpu from intel. If there was, it wouldn't be 650$, it would be more like 2k.
Also, that 10 gigs of memory does absolutely nothing other than take up space unless you are running 64 bit. Valve uses 32gb pc's with water-cooled overclocked 3ghz quadcores for building their stuff in hammer. Anyways, here is a little help if this is a serious post:
CPU- compiles map faster
Memory- helps compile time greatly. Makes hammer run smoother
Video card- plays the game better
If I were you, I would use some intelligence, and just get the vastly superior cash-for-power ratio of AMD. However, if you are complaining about having 10 gigs of memory and poor for gaming, I guess u can waste your money on an intel

.
oh, and last but not least I would upgrade that 250 WAY before that cpu. You can't even play crysis on max specs with it. However, my dual core amd 3ghz with 2 gigs of memory can run it on max specs with a 295.
