The lifetime warranty is nice, however the ASUS has a much better fan which will keep the card cooler and is necessary if you intend to overclock.
It comes with a 3yr warranty which should be sufficient unless you plan to keep the card longer than 3yrs which is unlikely....
Your PSU looks OK, good reviews but I'm dubious of Rosewill quality...only 2yr warranty whereas quality power supplies usually come with around 5yrs. I'll see if I can find some alternatives.
Oh I'll probably going to just stick with the other one you suggested cause I'm already cutting it close to my budget, thanks anyways tho.
I just watched a video that said that if i get the i5 2500k that i should get a p67-series mobo because it unlocks the core frequency of the cpu. So any suggestions on which one is a good mobo? (I don't really get the differences in mobo's)
That's not true, both AMD and Intel stock coolers are crap. I def recommend an aftermarket cooler for any overclocking.
Its perfectly true, and you've shown no evidence to the contrary. A graph we don't know the context of really doesn't cut it. Stock coolers may not be fantastic, but the only reason you replace one is if it's not sufficently cooling your hardware. Most people can easily get away with a mild OC if their case has decent cooling on a stock heatsink, assuming you don't live in a ridiculously hot area.
