Just grabbed the Fractal XL R2 for 89.99, the Team Vulcan RAM, the Asus card (one of the MSI coupons stopped working prematurely) and the 4670k/G45 Gamer bundle for 344.98 after rebates, discounts, cards, etc.
Crossfire is a ways off, if it ever happens at all, and from what I am hearing and reading SLI is better anyway. More importantly, I realized that I stream everything across my network, so the need for anything more than dual monitors is nil.
Next up: The XFX PSU, Samsung 256GB SSD, and whichever monitor I choose. Still undecided between the Dell and Asus. Does the Dell have any issue with motion blurring? I am not looking for CRT response rates, so I am thinking I can trade some response for IQ as long as motion does not suffer too much. I DO play a lot of fast paced games...
