Well I have just ordered the last of my upgrades (new ram/mobo/q6600) and I am faced with one last dilemma. I have been chomping at the bit waiting for Bioshock & Crysis (1&2 months left till release) and wondering if I should make the jump to VIsta for these 2. Something tells me although I am not totally sure these games will look much better in DX10, but will probably not run as well. Native res for me is 2560x1600 and I betting I wont be able to pull it and will have to scale it back to 19x12 at least. So should I stick with XP or make the jump to vista. While I am mentioning it, would 64 or 32 bit be better? If I do jump I want to order early and get acclamated to vista before the 2 releases. Would appreciate your thoughts.
