On my latest project I have 2 instances of Lecto for rhythms w/ boogex, eq and a screamer plug in front, two instances of LE456 for leads with boogex, eq, screamer, delay and reverb separately on both (no sends), and then for bass there's TSE BOD on one track and Lecto on the other (both with boogex, eq and comp on the BOD track)...I have a measly 2 gigs of RAM and set the buffer to 2048 ms and there's not a problem, no skipping no slowdowns. I woyuld think you would have an even easier time? My mobo is from 2007.
Maybe there's some background processes you need to kill, or run some malware/antivirus scans and check your process manager program to see if there's anything eating up processing power other than what you should have.
