OCZ Gold 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail

seems like a pretty good price with good reviews.
only negative may be the 2.0v requirement.

there are also some combo deals with a few EVGA video cards (2 have MIRs)
8800GT (129 AR) + RAM (50.99 AR) - 10 Combo = $169.99 total AR
9600GT (105 AR + 8.25 ship) + RAM (50.99 AR) - 10 Combo = $154.24 total AR

If I had a 64 bit OS, I'd take these for 8 GB O_O
