Get a GTX 275 instead of the 280. The 275 has a little less memory, and a smaller bandwith, but will still outperform the older 280.
You didn't specify if you were interested in overclocking or SLI. If you aren't, drop the board down to an ASUS P6T SE and save yourself some money. Same board, but with no support for SLI and without the advanced heatsinks.
Sorry, I missed that, corrected it though. I am not set on overclocking but was planning on doing some in the future. I'm not sure if that warrants an extra $130 on the deluxe board though. I may add a second graphics card in the future. Knowing this, do you think this board would be more acceptable?
When buying a video card, you're basically paying for which company you want to deal with in the event the thing malfunctions. I know that EVGA includes a lifetime warranty on the 275, and I don't know about the BFG.
As far as the different P6T boards goes, there's a LOT: The ASUS P6T SE has no support for SLI The ASUS P6T supports SLI The ASUS P6T Deluxe V2 supports SLI and has advanced heatsinks The ASUS P6T Deluxe supports SLI, has advanced heatsinks, and 2 SAS ports.
There's actually another couple of boards in the P6T family I think, but they aren't worth mentioning. What that all comes down to is make sure you know what board you are buying and what features it has lol.
From what I understand about what you want, the normal P6T that you linked to is probably the best choice. It will still do fine in light-medium overclocking, and has support for SLI in case you want to invest in another 275 in the future.
The build looks good. I haven't had the best of luck with the OCZ Gold RAM, but they seem to get good reviews overall. I, personally, would get one of the kits below instead, but I'm sure the RAM you picked will probably work fine.
