Prices on this stuff can change hourly, it's nuts. The 27" LED back-lite monitor I wanted was $299 for a couple of weeks, then bam, $400+ for a few days, then to down $350 where it held steady. I bought a competitors at $329. Same thing happened for my target power supply. Keep checking, and when it falls to what you think is a good price point, pull the trigger. I would expect some good pricing around Christmas.
I bought the XFX. It looked like the best deal at the time and the card seems to run well even though it's underclocked compared to the new ones. XFX hardware may be good (a friend likes them and they have good reviews) but dealing with the company is a PITA. Don't bother trying to download the newest drivers from the card vendors, go direct to AMD or nVidia.
The biggest problem I had was trying to hook up two 1 TB - 6GB/sec hard drives to the two 6GB SATA ports on the ASUS MB. Big mistake. A mechanical drive can't keep up with the port and the ASUS firmware still won't support 2 HDs on those ports. They did patch/fix the BIOS so it will support one, but not two mechanical HDs the last time I checked. A lot of people simply RMA those MBs because of it. I blame the sales departments at the HD mfgs for mislabeling drives that can't possibly keep the buffers full, and ASUS et al for not making the requirements clearer.
Oh, and does anyone know if MS is offering the family pack deal on Win7 again this year? It was only the Home edition, but hey, maybe you know folks who'd like to go in with you to reduce your cost.
