About time for a new computer

I am getting very close to blowing a lot of cash on a workstation machine. There have been way too many problems with my current computer that really put a clamp on my productivity. The prices are a bit steep when stepping foot into the workstation territory, but I should be able to save some of the money by building it myself. For starters, I have already have a new video card that may be able to do the job: BFG GeForce GTX260. The remainder of the system rings in around $1200.

TYAN S5396A2NRF

Intel Xeon E5410 Harpertown 2.33GHz Quad-Core Processor

Kingston 4GB DDR2 FB-DIMM PC2 5300 ECC

CORSAIR 750W ATX12V Power Supply

Western Digital Caviar Green WD10EACS 1TB SATA 3.0Gb/s Hard Drive

Microsoft Windows XP Professional SP2C 64-bit

Then again, it may be wise to just wait until Windows 7 is released next year and build a machine that is fully supported.
