I'm sorry if I don't have all the right details/links up. I'm pressed for time (gotta go to work), and I want to make sure I have a post up so when I come home I'll have someone telling me "go" or "no go."
It helps if we know what your budget is and what your monitors resolution is. Give us that info and someone on here can help you. Without that info I can't honestly say if that's a decent build or not.
For the actual PC, my budget is anywhere around $1000-$1200. That's not counting the peripherals. I haven't looked at monitors yet. I'll basically be buying whatever monitor works with that specific build, and work through whichever resolution is best.
Here's one worth looking at, you can always add another gtx 275 later on for SLI. If you google "ewiz coupons" or "ewiz promo codes" you can take another $5 - $15 off that mobo/cpu combo. This build is set up more for a monitor with higher resolution seeing how that board is a good one for SLI.
Here's a good single card set up for something like a 22" monitor with a 1680 x 1050 resolution. This UD3P board is really too small for two large vid cards, but it's perfect for a single card set up like this smaller case down below is... and seeing how one of those gtx 275's over clock to where it's running almost head to head with a gtx 285 it's a bargain for $200. There's nothing wrong with going with one good vid card now, then ebaying it or whatever in a few years and upgrading.
