Will these parts run well together?

I had a proposed parts list here yesterday but the main combo I was buying was discontinued today, so here is my new list. The goal for this list is to be able to max the Stalker and Crysis series (2xAA only) at 1440x900 on a 19'' monitor. Thats all I'll need it to do, really. The parts total to around $230, not including the GPU as I'll be waiting for a really good sale for that.

CPU+PSU combo

GPU- gtx460 either memory version, depends which goes on sale first.

RAM
I've chosen 2gb because I'm running 32-bit XP.

mobo
other mobo choice
I'm not 100% sure if they are good mobo choices, please make suggestions if you know of a better board for a very similar price.
If someone could verify that these would all work well together that would be great. Today is the last day for the rebate.

Thanks muchly.

My "or" mobo selection is cheaper than that with free shipping. Did you not notice the "or" selection? I'm gonna make that more noticable now.

Also I'll probably stick with 2gb for now so I can upgrade to 4gb with a 2nd 2x1 set if need be.
