True that, and cheaper.
Well, it's the dumbarse from Russia again. Hooray! Here's a tidbit of truth for you: I spent a $1000 on JUST my video cards, plus $300 on water blocks for them, stupid. My computer is home-brew. Like I said, and apparently you didn't bother reading, IT DEPENDS. Have you even considered that the OP may not be interested in building a computer? Of course not, because you're ignorant. Have you ever actually built a HIGHPERF computer? Sh1t, he doesn't even want to buy a new computer, regardless of who builds it. Save us all some time and please STFU.
Your point is meaningless.
Just because YOU spent 1000 dollars on graphics cards doesn't mean OP needs to.
OP's made a point on buying a new computer, you STFU.
Have I built a high end PC? Well, like you I have a watercooled PC (Custom WC).. I've owned.. ; 5970's,6870's,5870s,4870x2's,470's,5850's. So yes, I'm pretty high performance

.
A 300 quid prebuilt will use low quality parts, you can get a much better system for 300 quid.
That's my point I'm making. God knows what you're saying.
