Have the option to go either way with that board Jim, it has 8ch sound on-board, and I also have a creative 6ch PCI card. Probably go with the on-board sound in this case so there's less gubbins inside.

Not sure about the PSU, I've got an Antec 550W lump which has been fantastic, and I'm kinda loath to sling it out.
I'm sticking with the 9800GTX though, OCC say it's the best thing since sliced bread, and I've yet to find a negative review.
OK, bitten the bullet - and opted for a Thermaltake Toughpower 750W - I've already got a Thermaltake case, so I like the symmetry
