Well, I am looking at building a new system prior to launch as well, and I a bit like you have looked at this, and that and not 100% sure on which way to go......I see all this mean power.......and wants it.....oooh I wants it......but then I think. Hmmmm.....Do I really need that much to run anything, and just how far is it from having a kick ass system, to being insanely overpowered? lol
Well, we know for example, that this will run on a system as poor as that spectrum you had when you were 5, much in the same way as WoW does, so ultimately, power? You don't really need a huge amount. Graphics wise SW:TOR is not going to be as stunning as such AoC or LOTRO, so top end GFX is not overly needed.
That said, a good GFX will help with rubber banding and other ping/lag issues so worth it in my book.
Personally, though not sourced the final choices here, I am looking to build an i7 system, full DDR3 (At least 6 gig of it) And then its the usual ATI Vs Nvdia arguement in my head. ATI so quick...But brittle, Nvdia stunning GFX's but sooooo expensive in comparison to ATI.....hmmm...
All I would say if you are looking to build you new rig and want it to run as smooth as possible, is to ensure the motherboard you run is up to the task. I have long been an advocate that the single most important thing on a PC is the actual motherboard your running it on. You can buy all the other top end stuff you like, but if the motherboard is pants, you will never see the full benefit of all those shiny little gadgets you put onto it.
This is the bundle I am looking at getting as my starting platform.http://www.overclockers.co.uk/showproduct.php?prodid=BU-030-OB
I already have this as my PSU
Corsair TX 750W ATX SLI Compliant Power Supply (CMPSU-750TXUK)
And then like I said, its down the GFX i use really? And honestly this is one area I am still very unsure on as yet, part of me wants to go for 1 big bad boy MOFO GFX, the other to take two slightly smaller and SLI....hmmmmm.....
