I'd up the PSU wattage to a 750 watt just to be on the safe side. Or if you want to be able to buy another GTX 670 to SLI them later on you could get a 850 watt PSU. But this is all up to you. I'm guessing you're getting that case cause there's a $40 promotion on newegg(linked to it just in case you didn't see it).
these computers the more and more power efficient all the time.
with the 600 series, nvidia made a serious leap in power efficiency. this computer will top out at about 300 watts, so for single card use, there is no need to bulk up the psu.
with two 670's in this setup, you are going to be talking about around 500 watts. and since the cx600v2 only pones up 480 watts on the 12 volt rail, we're going to get in trouble.

I agree with both of the real suggestions above: if you're going to buy an Intel CPU, you have to overclock it to compete with the similarly-priced AMD model. Spend the extra $10 and get an ASUS board; they just work better. The one piece you absolutely don't want to skimp on is the motherboard, and not just because it's the hardest thing to replace down the road.
I'd also suggest you get an aftermarket fan/heatsink. Even a good one won't run you much more than thirty bucks, and they make a world of difference. Just make sure it'll fit in your case: a friend of mine had to dremel a hole in his side-panel to make his fit! Don't worry about your power supply not being able to power the larger fan; I'm running a similar setup with only 500W.
Speaking of power supplies, a modular power supply will really help you cut down on tangled cords all over your case, and they're becoming very popular (i.e. inexpensive) these days. I don't have one, but I wish I did. No real biggie if you don't, though.
And yeah, just get yourself 8 gigs. It's all you need at this point unless you're a big photo/video editor. Get two 4GB sticks (instead of 4x2GB) so that when you actually do need 16, you can just buy a couple more and fill the other two bays instead of throwing out your old RAM.
A last suggestion is to get a full-sized ATX board instead of a micro-ATX. They're easier to work with, especially since you're buying a beastly video card. Better airflow for cooling, too. This one's more personal preference, though.
A word on video cards: the numbers you don't understand (pipelines, bit, whatever) are more important than you think. If the one you're buying is $30 cheaper than the competition with similar first-glance numbers (clock speed, RAM), check those other numbers to make sure they're comparable to the more expensive competition so you don't end up with some arcane bottlenecking issue.
Great idea buying yourself a giant drive and a modest SSD; that will really help you out. Happy building!
what? overclock an intel cpu to get even with amd?
back in the days of pentium 4 and athlon perhaps. right now intel has undisputed performance advantages. there are very few "every day" cases where a modern amd cpu actually beats an intel.
an aftermarket heatsink is nice, but if this guy hasnt built computers in a while id suggest keeping it simple at first, then later on, if he feels the need, he can throw down some cash on a noctua or similar.
i agree with your suggestion about getting a full atx motherboard. if your chassi is big enough to house it, dont waste that space.
its extremely complex to compare graphics cards of different architecture to each other.
the best thing to do is to look at what actually matters, game performance, find a review that has all the cards you are interested in, and look at the graphs.
an example is the 7970 vs 680.
Card | Transistors | Core frequency | Shaders | Texture units | ROPs | Memory Speed | Memory Amount | memory bus width |
---|
7970 | 4.31 Billion | 925 MHz | 2048 | 128 | 32 | 5,5 GHz | 3 GB | 384 bit |
680 | 3.54 Billion | 1006 MHz | 1536 | 128 | 32 | 6 GHz | 2 GB | 256 bit |
seen like this, the 680 looks like crap. its got over half a billion transistors less than the 7970, way fewer shaders, tad higher fequency's but in turn way lower amounts of ram, as well as a significantly narrower memory pipe. the reason you cant just look at the numbers is because they dont show the whole picture. there is no universal "shader" they all use. the 7970's might be individually less capable than the 680's etc etc.
the real life situation is that the 680 is the better card, something you probably wouldn't have figured out just going by the specs.
the only time you can safely compare two cards, is if they are both the same card, and one of em has a factory overclock. cause then you know for sure, that that is the only difference, and since the factory oc card has the bigger number ( somewhere ) its going to be better, although a sane person would just overclock his card himself and save a couple of bucks.
