Of course I wont buy it I am a Windows 8.1 user which means I get a free upgrade
Judging by your posting history, it doesn't seem you'll have enough processing power to get the upgrade anyway.
In that case he should consider downgrading to XP.
Stay off the naughty sites, don't open any unsolicited mail or pop-ups, run a good firewall and Anti-virus (you know the crap you have to do on every windows regardless) and you should be pretty secure. Of course it lacks that ASRL or whatever it is called, but hell, Windows have never been crash hot with security and 10 will be no different so the marginal difference is nill unless you have $$$ to be made off the situation, then it is W2K, only real, times a billion.
But if speed is what you wwant, then 2.5 or 3 gig of processor, most of which is actually at your disposal instead of being sapped by the latest Windows. He'll be posting "like never before."
