If an I3 overheats in this machine, I'd seriously advise you to check the paste job and heatsink seating. That's like a seriously low TDP CPU. Although, yes, if that doesn't solve your issues maybe a better fan controller would. In this case, the fan was already seriously undervolted and spinning at a low speed, that's why the controller was an option. If your brother's machine doesn't have a similar issue, you'd have to find alternative solutions.

Dual 670's are only a tiny bit better than 780 Ti so definitely take 780 Ti and you wont have problems with SLI and stuff...

Dont buy it, save money at least for he 7770, this in not worth it...

Intel or AMD for CPU? - Will help determine motherboard

Yeah, of course I understand that. Mine's just an i5 dual core with hyperthreading (it shows up as four cores while it's not), so maybe it doesn't produce as much heat? Anyway it's worth a try to do the mod for me, I just don't have the money to buy a new computer at all. :/

Good on you though getting a Alienware.

Well, my brothers i3-2330m still overheats and Im thinking of making the fan controller for him....
