Okay, revised edition of my system:
Case: Antec P182
Again, clean look, good cooling.
Processor: Intel Q6600
Thought long and hard about the E8400, but decided to stick with Quad. Big performance gains for programs that will use it, but not really that much slower otherwise, especially if overclocked.
CPU Cooling: Zalman CNPS9700
Added a good cooler so I can overclock. Figure if I have high end parts, might as well overclock a bit.
Motherboard: ASUS Striker II Formula
Clearly overkill, but should be good for an overclocking n00b to have the snazzier functions.
Video Card: XFX GeForce 9800 GTX 512 Mb
Decided to stick with it, even though 2 x 8800 GT is probably better. No SLi issues to sort out, lower power consumption, and maybe I'll throw in another 9800 GTX later.
Memory: OCZ 2x2Gb PC-8500 Reaper HPC
Went with better memory, not too much more expensive.
Hard Drives: 4 x Seagate 500 Gb, 32 Mb Cache
Looked closely, and this costs less than 2 x 1 TB. Plus, running 4 x 500 Gb in RAID 5 gives me 500 Gb more space than 2 x 1 TB in Raid 1!
Optical Drive: Samsung 20x DVD writer w/ Lightscribe
Rationale: Nothing fancy here, but I can always through in a Blu-Ray later if I decide it's worth it. Right now though I just want to get this thing built.
PSU: OCZ 600W
Plenty for my system. Hopefully I get the version with the quiet fan
Buying this tomorrow after the game, so that's your deadline for comments. And thanks again to everyone!
