Two questioon for which I got for you is your system a 64bit system. Also one of the main reasons for which you've got the lag is your ram. I'd reccomend you addmore to your machine. Because if I'm not mistaken minimum is 4 megs. and reccomended is 6megs. Me I've got no lag at all because I've got 16 gigs of ram and I can take it all the way up to either 32 or 64 gigs not sure right off. But if you can add about another 8 gigs

No. You need a more capable system.
