Well, I am in need of a tad bit of help. Been looking around for 4GB (2GB x 2) RAM chips. I am in the process of gathering the parts to build a Quadcore system with Vista 64Bit edition and wanted 6-8GB of DDR2 800Mhz RAM. I tend to stitch large panoramas and don't want to run out of memory anymore. Having a bit of difficult located some of the more name brand of RAM... I keep hearing Patriot or Corsair RAM is the best choices? Any suggestions as to where to look???
