Unless you're partial to AMD; I go with a Intel based Motherboard and Intel CPU due to overall better performance. Also; for the $$$ you're spending on RAM, Why not spend the same and get 2GB x 2 = 4GB ie:
OCZ Reaper HPC Edition 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2RPR800C44GK - Retail $109.00 w/ $25 MIR from newegg.com
