as ex said, it depends on the res, but it IS possible.

i also want to add that it also depends on inputs. A/V amps are a good way around this issue.

FWIW, I 6 table my big CRT at 2048x1536...there's overlap...but I can deal with it (then I have 3 on my 15.4" laptop with lots more overlap).

Throw - any modern Dell tower (non-budget) should be able to run 2 monitors ok.

I'd get one with at least a 250 gig hard drive, 2 gig RAM, a dual core processor of some sort, a 256M or higher graphics card and basically you are set for Poker/PT and browsing. I bought one specced like that for $750 well over a year ago in the UK (not the cheapest place to shop) so my guess is you should be able to pick up what you need for $500-$600 or so.

I would read the reviews to try to find a quiet one - once a PC can do what you want it too, then stuff like lack of noise becomes more important than other bells and whistles.

As for Prima and B2B, I don't think B2B allows US players.
Several Prima sites do allow you to play from the US I think. You might like to speak to T-Rod about the best prima sites. My favorite one got taken over last month and he was able to point me in the right direction to find a very good replacement..

If you play the 6 max $100 at Prima you are also likely to find me (Excession).
Also at Prima you can datamine with PT, so you should always have stats up on your opponents..
