I am thinking about upgrading my system to a i7-975 with 12 to 16 gb memory. I do not plan to overclock at all. My current system is a E8600 with 8gb memory (maxed out on board). I do alittle video editing, watch tv through tuner card, and play wow (alot of times having 2 accounts open on different monitors). Will I see any difference with this upgrade? My other option is getting a new board to support my current processor and adding more memory. Either way I would have to buy more memory. If I stayed with DDR2 I could use some of my existing memory and finish the upgrade to 16gb at a later point, but how would this be as far as performance compared to going with DDR3? Any suggestions would be appreciated.
