I've been reading through a lot of forum posts on this so I apologize if bits and pieces of these have been asked elsewhere, but I thought I'd give it a shot. I have a early 2008 2.8 octo (in my signature) that I use for my home music production and for photo processing with CS4, so graphics cards are the Radion X2600 (2 of them for 3 monitors) because I wasn't really worried about it. I do most of my gaming on Xbox 360 and PS3. I have an XP boot camp partition as well. I'm all of the sudden interested in doing some gaming because of the free Crysis mod "Mechwarrior Living Legends". So here's my question: 1) I'm pretty sure that Crysis will run terribly on the current graphics cards I have (haven't purchased Crysis yet). Should I buy a ATI 4780 card off of ebay and flash it, or will the new base video card the NVIDIA GT120 be better than my current card and adequate for it? (trying to spend less than $200 if possible for this) 2) Should I keep XP or should I pony up for a Windows 7 install? 3) If I'm buying this stuff should I just build myself a dedicated windows machine? Appreciate the opinions and help! Thanks!
