I think I'll go with the ASUS MAXIMUS IV, seems to offer some nice things, it's expensive, but IMO, it's worth it.
Also, yeah, thought about going for the i5 2500K, but decided that the 2600K was better, even with the $100 extra.
One thing kinda bothers me though, I've read that the stock heat sink/fan doesn't work properly, so I'll probably have to look for something else in that field.
So, the list so far:
Cooler Master HAF X
CORSAIR XMS 4GB 240-Pin (2 maybe 3 of these. )
SAPPHIRE Vapor-X 100281VX-2SR Radeon HD 5870 1GB 256-bit GDDR5 (Thinking of using 2 in CrossFireX what do you guys think?)
Intel Core i7-2600K Sandy Bridge 3.4GHz
ASUS MAXIMUS IV EXTREME (REV 3.0) LGA 1155 Intel P67
Thinking about keeping my HDD for awhile, though I may buy this:
Western Digital Caviar Black WD1001FALS 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5"
And maybe, just maybe, an SSD, though that's probably not going to happen.
So, what should I look for as far as PSU power goes?
Also, I'll probably go with the ASUS VH236H 23" for my monitor, since the one I have is just 17"
