rust 8800gtx does not have a competitor the x2900xt is in direct competition with the 8800gts 640MB
mobo's: don't take my word that RAID 0 sucks across all board but this is my personal experience on the DFI with the RD600 chipset - RAID 0 only caters for 16bit allocation size too small for my liking as I have huge mother files as well as thousands of smaller files so anything without 64bit does not work for me

My mobo atm: Asus P5B-Deluxe nice board, has everything dual lan, firewire, the works BUT feking mobo has heat pipes from the NB to the VReg and I cannot cool my vreg down with a fan they provided as my radi is in the way.
Worst off my firewire transfers @ 5MB/s instead of the sustainted 28MB/s same applied to my USB until I found a beta INF driver - stupid all in 1 crap that is 100% worse than the AMD-Nvidia chipsets.
also I feel that my 2x250 in RAID 0 is much more sluggish in this intel than it was on my AMD 4200+ dual core...
LCD: Samsung 22' is the way to go benq is really shit for movie playback but good for gaming... samsung = good looking, awesome gaming, decent movie playback!
Intel is now moving to DDR3 if you didnt' know that already... so RAM... lets see DDR800 is more than sufficient unless you plan on pushing the CPU to hell and back then you'll need 1333MHz one...
Only decent thing with this intel is the ALT-TAB works extremely fast compared to my AMD.
Personally I don't think paying over R2000 for the E6600 and over R2000 for a decent mobo justifies buying a Intel... for that price you could get the AMD 6000+ @ 3GHz and have tons of space for more overclocking plus the AMD mobos don't cost you over 2k for a decent one.
Oh and you would at least have more life in a AMD than a INTEL... I mean what... the next upgrade I ahve to do will be new RAM, Mobo and CPU...
if I'm correct AMD only cycles thru different pin/ram once every 12 months... intel? every feking 4-6 months... doesn't justify me buying DDR3 with a new mobo just so I can run a decent CPU
Personally I think you've missed the whole Core2Duo hype... it time to consider the next generation if you going the PC route
