It's better to use a ssd without SRT. Especially if your spending enough for a i7, I don't see why you wouldn't get a 60gb+ ssd. A ssd alone can reach its max performance immediately rather than be limited by SRT deciding what needs to be cached off the hdd and then being used off the ssd. Without SRT you also have direct control over what files go on the ssd, so you can put the files you want on it, rather than some program trying to figure out what you use/want on it. P67 is not better for gamers than z68, they perform exactly the same on games but offer different features, none that games need.
