i havent built a pc in about 3 years as my last one worked great and most new PC games are dogshit. its time to build a new one though and this is my first attempt to wade back into the pc hardware world. my biggest questions are about mobos and ensuring that im crossfire ready, but any and all advice is much appreciated.
heres my working list so far:
vid: Radeon HD 4850 x2 (crossfire setup)
power: CORSAIR CMPSU-750TX 750W ATX12V / EPS12V Power Supply -
mobo: help! no good at figuring these out..... looking at the following...
DFI LP LT P35 T2R LGA 775 Intel P35 ATX Intel Motherboard
ASUS M2R32-MVP AM2 AMD 580X CrossFire ATX AMD Motherboard
ASUS P5Q LGA 775 Intel P45 ATX Intel Motherboard
that more or less does it besides HDD and sound card which im not worried about right now. money is no object for the most part, within reason (games dont effectively use quad core so why pay for it, for instance, DDR3 seems really not worth the price bump, etc)
basically im wondering if thats the best processor i can get, and if my mobo can support an intel processor AND crossfire those two cards at the same time
thanks much for your help. im hoping this machine will handle my gaming in kickass style for at least a couple years.
The ASUS P5Q will Crossfire the cards, but only at x8/x8 speed. Apparently there's little difference at lower resolutions between x8/x8 and x16/x16 Crossfire, but as you increase the resolution there is a clear difference. There's a review from tweaktown that's going around showing the difference, but I would at least verify their findings somewhere else.
At the level you are looking at, definitely go with the e8400 (or e8500 for $15 more). There's an extra .5 multiplier on the e8500 if you're planning to overclock, otherwise I don't think it makes much of a difference.
You probably should be looking at an x38 or x48 board if you want to take full advantage of your video cards.
1. Proc : Q9450 (Quad) or E8500 (Dual), it is your choice.
2. ASUS P5EX48 or Gigabyte GAX48DS4
3. Zalman CNPS9700, Xigmatek HDT-S1283+bracket, or Scythe Orrochi.
4. The rest is good.
5. If money is not an issue for you than why don't you pick 2xHD4870 instead of 2xHD4850.
You are right about those DDR3, right now DDR3 is still way too expensive.
thanks for the replys guys, good to see people faithfully trolling these forums at work.
guanyu: thats a good question regarding the video cards. basically, the benchmarks ive seen for the 4870's versus the 4850's seem to be extremely close, and the price difference, though not huge, is significant i think. that was just a judgement call i made as "not worth it" but i could certainly be wrong. do you understand the difference in the 4870's to be worth it?
zvandy: thanks for the info, its exactly that sort of thing im worried about but apparently to dense to figure out on my own. would the ASUS P5EX48 guanyu mentioned get me x16/x16 crossfire?
also, though ive never OC'ed before, all the reviews on these parts and builds ive read are pushing me to do so. these toys seem to have a reputation of being fantastically stable. thoughts?
looks like the asus x48 is gonna be my mobo then. thanks for the help!
google is telling me august/sept on the 4850x2 and 4870x2 cards which sounds perfect (im building for an october release). ill grab that aftermarket cooler regardless of whether or not i OC, but what the hell, i think i should give it a try to get 3GHz out of that processor. seems pretty standard from what im reading.
i think that oughta do it. thanks again for the help
Except for the Zalman 9700, I'm an advocate for the education of Zalman's dated designs and overpriced coolers. The Xigmatek S1283 is the best choice (add 800 or 1200 RPM Scythe Slipstream for awesome performance - thermally - and near silence).
And your OS should definitely be Vista 64 (to take advantage of all your memory - system and graphics).
i was privvy to vistas horrible launch, yes... ive seen that SP1 is out though and ive heard that has helped a lot. im browsing around tweakvista.com trying to get comfortable with the idea. i have a copy of vista 64 handy, so maybe i should go ahead and use it.....
I was sceptical for a while, but when I switched my HTPC to Vista about a month and a half ago, I was sold. Yes there are some new ways of doing things you'll need to get accustomed to, but that goes with any OS switch. I personally really like Vista. Since then I've switched my girlfriend's computer to Vista and will soon make the transition with my desktop.
