OK, really on the fence about this. In the next week or so, I will be buying either a used SP3 or SP4. It would be used as my main machine. Mainly web browsing, software testing and running virtual machines. Trying to decide between and i7/256/8 SP3 and a i5/256/8 SP4.
The SP3 is about $200 cheaper and it seems have way less problems than the SP4. Looking for opinions on whether the SP4 is worth it. Please help!
