yeah the 8800gtx is a good card and i was looking at it myself as it has the extra ram but found for the money you could get a 9800gtx which is about 10-15% quicker and unless your planning on playing games on 22"+ size screens at massively high res you don't really need the extra ram.
but the problem with the 9800gtx is the 8800gts! lol its that question of is that 10-15% gain worth the £40 price bump lol

the HANNS.G screens the better of the two with a much better contrast ratio although even thats not great, if your going for a screen you can't really go wrong with an LG as i think they are something like 5000-1 (5x what the HANNS.G is) with a 2ms response time
