It looks as if this is somewhat of a spare no expense system, but i'll put in my input.
First off, i have to reiterate the fact sixshot made in buying a very good power supply. FOR THIS TYPE OF SYSTEM, THE POWER SUPPLY IS PROBABLY THE MOST OVERLOOKED ITEM. You must get a SLI certified power supply regardless if your going to overclock or not. This fact is multiplied to some degree if you do choose to get Dual Core.
AMD is obviously the better choice and although the single core AMD is a fine purchase, you might want to look at Dual Core if you don't necessarily plan to upgrade anytime soon. You will probably lose a couple of percentage points in the frames per second segment, but not by much. Also, newer games might become multithreaded applications as well so that MIGHT factor into your decision. If you do plan to upgrade relatively soon however, then just get the single core and be over with it.
The Nvidia 7800 GTX is a fine choice, but i MUST SAY, that every high end card that has come out with SLI compatability, the SLI function becomes nill when the next generation comes out. If you look at the product cycles of SLI, they do not make any monetary sense to the consumer unless they intially buy both video cards outright. Case in point the 6800 series and the introduction of the 7800 series. Even if you used two 6800 GT's they were trumped by a single 7800 series. True that this might not be so the next product cycle, but i wouldn't count against it. Crossfire i somewhat advise against it because of its price and relatively young product cycle. Although, All-In-Wonder cards have always been a favorite of mine, i would just wait for cable card supported TV Tuners from ATI if you would choose to go that route and if you do so, windows media center is also an option.
Memory...pretty much a standard affair; OCZ, Micron, Corsair is the most likely way to go and 2 gigs is fine. Just remember good latency timings and you should be fine. HOWEVER, if your gonna build this system build it relatively soon or else YOU WILL BE KICKING yourself in the ass when Socket M2 comes out most likely over the summer. Just in case you didn't know, Socket M2 is AMD's new chipset that uses DDR2 RAM...drool.
As for the hard drive i suggest two, not to to be put in any fancy raid configuration. What i do is have one drive for applications (i.e. windows, games, program files) and another storage drive (music, video clips, photoshop files, documents) This way i can reformat the program hard drive at whim, because no matter what your computer will bog down from surfing the internet also making it somewhat easier to backup data.
And for god sakes please remember to use a case that has ample cooling and room for all these components. The 7800gtx is a pretty damn big card, and having it touch stuff isn't the best thing in cable management.
