Your PC Gaming specs
I've just recently bought a new base unit. It is a Sandy Bridge 2500K, unlocked with 8GB ram and a GeForce GTX570 card. Works for me!
What about anyone else?
Do you really need 12GB RAM? 
£90 for 6gb, £110 for 12gb, not really a hard choice.

I did briefly have a very nice overclocked 'Sandy Bridge' based setup but it's had to go back due to problems so I'm back to using my trusty 2 year old gaming rig. It's nothing very special but it's still capable of running Crysis smoothly on max settings at 1280x1080.

Beautiful monitor you got there. I used to have one, but couldn't cope with the wide gamut. Do the games you play have colour management?
I've been waiting for the next gen of AMD cpu's. (bulldozer) to upgrade from my phenom x4 processor.
Using my laptop for now. Don't see the need for an uber system, they cost an uber amount and my laptop runs everything smothly for the moment.
It's a 6GB ASUS G73 i7 Q720 1.60 mobility radeon HD5870. WIn 7 HP 64bit.
To be honest I'm not a mad gamer. Playing Portal 2 just now though.
cheers, I bought it mainly for Photoshop use to be honest. I'm not an all out gamer...but I love Fifa on the PS3 and play the odd FPS on the laptop. I gave up mad gaming with Quake 2., which for me is still the best ever online free-for-all deathmatch experience

Just installed new GPU so getting to grips with it now, registered with "Steam" so looking forward to gaming. My first game, Dragon age origin's...
Nice one Dave. Steam is very good. You'll have to try Crysis 2, Counter-Strike et al.
Your Windows score will be the HDD lowering your score, I'll wager. A nice SSD would be a boost, although bang for buck they're expensive.
