I've read on many websites, checked wikipedia, checked benchmarking, searched TPU. I may be blind, but I saw nothing on the performance gains of using, say, a 4 gig readyboost drive on a system with 4 gigs of, say, 4-4-4-12 RAM. So, I'm installing X64 vista on my computer tomorrow, my specs are as follows: E6750@3.0GHZ stock volts, 4 gigs crucial ballistix running at 2.2v 4-4-4-12, evga 8800gt ssc, and a gigabyte ga-p35-ds4. I currently run XP 32 bit, so it's going to be a huge difference. I've already found drivers, etc, that I need for x64 (or at least most of them) and put them on my other hdd. However, I've been thinking about readyboost. I constantly see readyboost 4 gig drives on sale for around $20, with good read/write times (around 15/9). Now, would I see ANY increase in performance from a 4 gig readyboost drive when I already have 4 gigs of ram? I'm sure it's been done before, just didn't find it in searches. Thanks TPU.
