So I was going to get a rather high-end laptop for around $1300. Then I decided "hey, if I'm paying that much anyway, why not get some stuff I don't actually need, but would be fun to have anyway?" So now the price on it, with all the other **** I want, is $1700. 2GB RAM, 512MB dedicated GeForce, dual 80GB hard drives, among other things. So here's my question: currently, I'm planning on a Core Duo 2 T5500 processor (1.66 Ghz). That's included in the price. For $150 more, I could get the Core Duo 2 T7200 (2.00 Ghz), which isn't just faster, but it has a 4MB L2 cache... double what the T5500 has. So how much of a difference would that make, in practical terms? Yeah, I'll do some gaming... also some video editing and system intensive programs like HP Service Desk, Photoshop, etc. I do know 2MB is already very large for a L2 cache, but is it worth it to just pony up for more? Also... how beneficial would it be to set up a RAID 0, instead of just leaving the hard drives separate and perhaps using one as a program drive and the other as a scratch disk/media drive?
