Ahh, Dell is already out of the question. I won't be buying it.
I'd rather assembly it myself at this stage. I know I should wait until January so prices will drop a bit but it is really hard waiting another month.
Now, I'm already 100% sure about the CPU, MoBo.
For RAM, I know I'll be getting a Corsair 6GB 1600Mhz 7-7-7-24 16.5v. I don't like the high voltage but the low latency looks great. High voltage = higher temperature, right? Something I'm really trying to avoid.
GPU: GTX 460. But there are different manufacturers for it. MSI, EVGA, nVIDIA, etc... I don't know which one should I go for. So I'll pick any.
Well, the rest is just... the rest!
