id say its as good but kinda rough on the video card.i wouldnt oc the card while doing it so it runs cooler.
to be honest with you i swear by F@h for burnins can do it and use the rig at same time.heats up cpu and works it as hard as prime.ive been able to squeeze 2more fsb outa my 650 tbird with it and i never believed in burnins.
i dont wanna push the F@H issue as it used to annoy me at times people askeing me too.but with prime you run it for days and its gone just spent electricty. why not use that time proctivley?
btw dont bother with toast it sux badly,mager errors all over the place and crashes too. lol really bad experiance with it myself.
