megawatz, thanks for the reply. I think my dad is using some 2gb system or less right now for his work. It' s just family videos he does. Why not go over 8gb of ram? Or does he only need 8? And I think I'll probably go with an i5 3570k and just overclock it for him, im not sure he needs the power of a 3770k. It's not a big deal either way, I'll think about it though.
AS5 is as bad as stock pastes these days, and I'm pretty sure the stock paste used by intel under the IHS is better than AS5. It's over a decade old, it's horribly outdated. People got improvements using AS5 during delidding because reducing the gap by removing the glue is what drops temps, not replacing the paste.
AS5 is just some of the worst paste out there these days. It's so terribly dated. Problem is that it great 13 years ago, so people bought it, recommended it, and a vicious cycle continues because people generally get a single tube and that lasts them a lifetime of builds (or least 15+ years, ie 2-4 builds).
CLP/CLU would be a huge boost over AS5. I can't stress enough of how terrible AS5 is. Check out my review here of thermal pastes:
I dont compare AS5, but I compare PK-1 to PK2/PK3. PK-1 is a bit dated too, but it generally is considered 1-5*C better than AS5 - a bit better, not much. In the tests I do, PK-1 gets blown away by a modern paste like PK-3. And with thermal pastes, a 1-2*C difference is considered extremely significant (its just paste after all), so the fact you'd see possibly 10*C difference in PK3 and AS5... i wouldn't be surprised in drops of over 15*C in CLU/CLP vs AS5.
TIM differences are also exagerrated under the IHS. What might be 'only' a 10*C+ difference that CLU/CLP has over AS5, would easily become 20*C+ when under the IHS.
It isn't so much that there's huge differences in pastes or CLU/CLP is so awesome (although it is, it's not a normal paste like PK3, Gelid GC extreme, NH-T1, Masscool, and other modern pastes that are at least 5-10*C better than as5), it's that as5 is junk.
It came out over 13 years ago. Think about how far along GPUs and CPUs have come in 13 years. If you don't want to drop $20 on CLU/CLP, buy an LED or something else you might need at frozencpu and use the 5.1% discount so you get free shipping and 5.1% off ship. You can also find a modern paste on Ebay in 1.5g quantity around $4 shipped, like PK-3, that is significantly better than AS5.
Let me put it this way - the difference between PK-3, and PK-1, a paste that is consistently ranked a couple degrees higher than AS5, is a larger temp drop than I got from going from a Hyper 212+ to Corsair H50 water cooling.Edited by Belial - 1/17/13 at 1:59pm
