Hey guys, I'm putting together a mid-upper performance PC. The effect I'm really trying to get here is good performance while not ludicrously expensive (no 1k processors). Also, I've only built one PC and that was about 2 years ago (hence the replacing now) and if you guys could lemme know if I forgot anything and/or some of the stuff I'm buying won't be compatible with other stuff, that'd be awesome. Anyways here's the specs -

Thermaltake Tsunami ATX Case
Two WD Raptor 74GB 10k RPM ATA150 hard drives. (which works with raid, right?)
Asus A8n-SLI 939 deluxe mobo
AMD Athlon 64 X2 4400+
XFX Geforce 7800GTX 256MB vid card
OCZ 2GB (2 x 1gb) 184-pin DDR 400 ram
Windows media edition

So yeah, that's what I have in my "wish list" I suppose. Those two raptor drives would work for RAID right? I don't really know anything about RAID or have ever used it, but I hear it's good for data transfer speeds which leads me to believe it'd be solid for my pokertracker database. Thoughts?

I'm also not sure on the video card, is getting 7800 GTX over a GT worth the price difference?

Also concerning the SLI mumbo jumbo - I hear that if you plan on dual monitoring, the SLI won't do any good. Is this true?

Thanks for looking guys.
