I don't agree with the use of that "guide" since people's intended uses and their expectations are far too diverse to just give a "suggested" build for a specific price range.
Personally, I wouldn't get Core 2 at the moment. I'd look at either the Core i7 for out and out performance, or AMD for value. Core 2, and the socket 775 motherboards, are reaching the end of their useful lives.
Tell us your budget, we'll take a look. I will say in advance that I think if you're looking at that sort of price point for a graphics card, I'd look at a GTX260, or the 4870.
It has 35amps on the 12 volt rail as opposed to 27amps on the budget build in the guide. A little more money, however it will provide more upgrade-ability
AMD Phenom II X4 3hz CPU with the GIGABYTE GA-MA790FXT-UD5P bundle here: http://www.newegg.com/Product/Comb [...] mbo.237638 Frome reviews, this board overclocks well too, so if that's your bag, you're in luck. If it's not, the option is there if you feel more confident later.
Sapphire Radeon 4870 found here is the Vapor X one, for about the same price as the standard one: http://www.newegg.com/Product/Prod [...] 6814102825 In theory, the cooling should be a bit better on this one. I've no experience of it myself, but I do have the normal Sapphire 4870, and really like it.
RAM - 4gb of G.skill DDR3 12800. Can't go wrong really. http://www.newegg.com/Product/Prod [...] 6820231193 You don't really need any more than 4gb at the moment, but if you're feeling flush in a couple of months, you can add to it.
PSU - 500w OCZ ModXstream. http://www.newegg.com/Product/Prod [...] 6817341016 $59.99 is a good price for this anyway, but even better with a $20 rebate. I've gone for this one purely because it's a brand I know. The one sportsfanboy recommends may well be better, I just get nervous about a PSU I don't know.
All this comes to $599.95. It's not bad for upgrading later, as the AM3 socket is new, so you should be able to replace the CPU later if you want. You can also drop in another HD 4870 later, and run crossfire when the card is cheaper. If this is something you want to consider, you might want to think about spending slightly more on the PSU ($40) and getting this one: http://www.newegg.com/Product/Prod [...] 6817341002 or this one: http://www.newegg.com/Product/Prod [...] 6817371026
The one I've picked will run this system, no problem, but these two should run the crossfire if that's what you want later. I would prefer the Antec one, as it's on AMD's approved list for 4870 Crossfire power supplies, which is here: http://game.amd.com/us-en/crossfir [...] 0HD%204870
I quite enjoyed that actually! I hope it's of some help. Obviously, if you put it all together and blow a hole in the side of your house, that's not my fault. Buyer beware
