Hey everyone, first post here. Just thought I would drop in and share this with everyone and see what they think. Firstly, I am a gamer and play the latest high end games. I also record guitar and vocals through a USB interface into an audio suite and mix and produce (or try to and pretend I know what I'm doing, anyhow). Right now I am running: Intel Core2Duo @ 1.8ghz 4GB DDR2 Seagate 720GB Nvidia GTS 250 Vista 64 I am looking at getting into a nice cheap upgrade that looks something like this: AMD Phenom X4 965 @ 3.4ghz 4GB DDR3 1TB HDD Radeon 5770 Win 7 64 My questions are: 1. If I have a 80mm (I think) fan on the side of my case, one (60mm?) in the back, and obviously the PSU fan and heatsink fan, should I take any other heat dissipation measures to accomodate the increase in hardware? 2. Is the jump from DDR2 to DDR3 drastic in normal computing/multitasking/processing? In gaming? 3. Would I see $70-$100 worth of performance to jump to an i5 with an 8mb cache? This would obviously alter my Radeon decision and my mobo selection. 4. I can pull this off under $400 shipped. I suppose im looking for a little comfort pat on the back saying "hell no, theres not THAT much of a difference going with Intel given this price to performance ratio." Thanks in advance.
