The P7N Diamond is high on my list of potential motherboards for my next build, can I expect to get 8gb of ram working on this motherboard (Patriot Extreme Viper)?

Also, if I were to buy this board along with a GTX 280, how likely am I to experience video corruption? These are the two main issues that have prevented me from going ahead with my next build, and I'd like some first hand responses from experienced P7N users, so your input would be greatly appreciated.

Here is what I'm hoping to put together:

Intel Core 2 Duo E8500
EVGA E-GEFORCE GTX 280 Ftw
Patriot Extreme Viper 4GB 2X2GB PC2-8500 DDR2-1066 (x2)
Western Digital Caviar SE16 640GB (x2)
Bgears B-ENSPIRER 7.1 DDL DTS
Noctua NH-U12P LGA775 AM2 Heatsink
Noctua NF-P12-1300 120MM Ultra Quiet Cooling Fan
Corsair TX750W 750W
LG GGC-H20L BLU-RAY HD-DVD Reader BD-ROM
Antec P182 ATX Black Mid Tower
Logitech G5 Laser Gaming Mouse
Logitech Internet 350 USB Keyboard Black

Chances are if I feel like the video corruption issue is going to be a huge problem I'll probably go for a P45, but I'd prefer to buy the P7N and keep my SLI options open...
