What's your budget? What are your applications? How long are you willing to wait?
Do you require a keyboard / mouse, speakers or a monitor?
If the purpose is primarily gaming, I would suggest the i5-2400 / 2500K - you'd get much higher frame rates and single-threaded performance with the i5, alongwith comparable multi-threaded performance.
The catch here is that Intel is recalling its Sandy Bridge chipsets due to a design glitch.
I would suggest waiting till April when the revamped chipsets hit the market in volume, if you can.
Else, the 1090T's gaming performance is not that much different from the 955BE, so the latter might be a good idea.
I like the choice of RAM - nice, tight timings at a good price.
For the HDD, however, I would suggest the Samsung Spinpoint F3 1TB. It's faster than the Seagate in most benchmarks and offers the best bang-for-buck, unless you can get the Seagate significantly cheaper.
Thanks for the reply! My budget is around $1000-$1100, and I wont be needing any monitors or keyboards or anything. Basically the reason I wanted to build a new pc is to play World of Warcraft on my 30in. Dell monitor on Ultra settings at 2560x, something that my Dell XPS 400 cannot do. I also don't want any graphics hiccups when doing 25-man content. I use two monitors also, the other just for web surfing or youtube. Will the build I posted achieve that or am I completely misinformed? Thanks for your time.
I take it you're unwilling to wait for the patched Sandy Bridge mobos to hit the market.
Still think you won't need a 1090T. An OC'ed 955BE should be just as good for gaming.
And 'batuchka' is right, if you don't plan to Crossfire, just get an 870 chipset based mobo, instead of an 890FX based one.
Save a bit this time on the non-essential components, and then upgrade again when Ivy Bridge comes out in a year. Better yet, wait until Haswell before upgrading...
Personally, I stick to Asus and Gigabyte, and maybe MSI. I wouldn't take the ASRock board because it has only a 1-year warranty.
For the graphics card, I think you'll need a better one considering your 2560x1600 requirement.
The 6850 just won't be good enough for Ultra at reasonable frame rates and the 6870 might be cutting it a bit too fine, if you would like to play other games. I second the 6950 2GB that 'batuchka' suggested. It'll give you an average of at-least 5fps over the 1GB model. It will also give you some freedom to play other games at good quality settings.
The best part would be that you have a chance of unlocking the card to a 6970 by flashing the BIOS - a free performance upgrade. This may or may not work, so do it at your own risk. The XFX warranty should have you covered in case of a mishap, though and I suggest you give it a shot. http://www.techpowerup.com/137140/AMD-Radeon-HD-6950-ca...
Do you live near a Microcenter? They've got the cheapest rates. If not, you might want to check if shipping from them is a viable option vs. NewEgg.
Here's the revised build I suggest:
(Note: All prices are from Newegg with shipping costs included where applicable.)
Optional, but it would be a good idea. I would have suggested the OCZ Freeze Extreme - it's cheaper and gets better temps - but it's out of stock at Newegg. The absolute best - the TIM which has consistently received superior reviews would be the Coollaboratory Liquid Pro, but it's a little difficult to find. BTW, all these pastes are supposedly better than the Arctic Silver 5 and equivalent to / better than the Arctic Cooling MX-2.
But if you get restless, just grab the PSU and the graphics card and install it in your current machine. Those two components you'd be retaining anyway in case of an upgrade. I am assuming that your specs match those here, which means you have at-least 1 x16 PCIe slot available.
Until you upgrade completely, your CPU would probably bottleneck the GPU, but, heck, what have you to lose? At worst, you'll have a PSU and GPU lying around idle for a couple of months...hardly catastrophic.
Ok, I will consider that. I was under the impression that the power supply connectors in the dell xps 400 were proprietary and a different power supply could not be connected to the motherboard, as the motherboard is also proprietary. (BTX) Is this true at all?
