Yeah, but he has a 330W and I have a 460W (or something close). I'm just sayin' the PSUs Dell uses now tend to be able to push out more than you'd think they can. I'd probably still suggest he get a new one if he wants to step up the video to something beefier.
I really disagree with the push for overclocking anything. If the dude's working on a budget, you can bet he's not dropping a few thousand for modo or Maya or Cinema4D or something like that for pro-level 3D modeling. At that point you're looking at something like a Mac Pro class workstation ( http://arstechnica.com/gadgets/2012/08/ ... cle-ahead/ ) and a Quadro or FireGL video card, not trying to shoestring budget up an existing Dell.
That being the case where 3D is a hobby, not a job, I think overclocking is an unneeded expense to try to chase. Given the fact that the CPUs provided to OEMs like Dell are probably not the same as retail CPUs, it could be pretty hit-or-miss. Benchmarks at Tom's seems to show that 3.8 is a better overclock goal than 4.0 as in some cases 3.8 performs faster ( http://www.tomshardware.com/reviews/ove ... 268-8.html ). Heck, they even recommend staying at 3.66 if the OP really wants to go that route.
And the power used seems pretty harsh, too. But that's just my opinion on it. The dude's got a Dell, I can't imagine he's a hardcore homebuilder. I pretty much agree with MrJP though I still think he should dump in more RAM if he wants to mess with Blender or something of the sort.
