Currently have an i7 920 with 3GB of RAM running Win7 64bit and I am looking to upgrade the RAM & HDD (soon, when prices come down again!) to improve all round performance. Don't really use it for that much photo editing, but do a bit of video processing/converting. Some gaming as well. I have done the Crucial scan and it has told me what is compatible with my motherboard, a MS-7522 (X58 Pro-E SLI). I know that 12GB (4GBx3) would be overkill for my uses, but for the sake of say £20-£30 extra, is that what I should get? Or just go for 6GB (2GBx3)? One last question, as it is triple channel at the moment, could I get an 8GB kit 4GBx2, and get that to work on my MB? Thanks.
