Maximum PC

I have a pretty powerful computer that I am trying to replace and get some cash out of it at the end. These are the specs for my current machine.

Processor: Intel Core 2 Quad Q6600 2.40Ghz G0
Memory: 4GB DDR2 800Mhz PC6400
Graphics Card: XFX GeForce GTX 275
Motherboard: XFX nForce 680i LT SLI
TV Catpure Card: Pinnacle PCTV HD 800i
Optical Drive: LG BDROM + HDDVD Drive
Hard Drive: Seagate 320GB
Chassis: NZXT Zero 2 Full Tower Case
PSU: Ultra 800 Watt Modular Power Supply
Additional Fans: 4 120mm Blue LED Antec fans w/speed controls

This computer is about a year old and custom built by myself. There are only 2 issues with the computer. The first is that during bootup, the graphics card makes a fan sputter but as Windows loads, the fan noise gradually decreases and the fan is still spinning. The other issue is taht Windows 7 RC1 is currently installed and as the release candidate will do, it will shut down every 2 hours starting in March and ultimately stop being active in June of 2010. I have spent nearly $1500 on this computer and cummulatively bought pieces over the last year.

Here is the computer I wish to replace it with

This has double the memory, faster memory, faster processor speed, larger hard drive, and a permanent copy of Windows 7 64-bit. It also has a year warranty I will most likely extend. As posted on Tigerdirect.com, this new computer is about $750.

I'm looking for a stable quotation of my computer as the reasonable price to sell it for. On top of that, I would like any opinions on the replacement computer as well as any suggestions on other computers to find.

I moved this thread to the appraisal section, make a separate thread for your new computer buying questions in the HMB/HMB section

I would sell that computer for around $650. However, that Gateway that you picked out is way worse than your current computer for gaming.

have to ask,
why would you buy a store built pc?

you have the basis for a good upgrade already
keep the case
the video card while not the top of the line was a good one, you probably just need to clean the dust bunnies out of the fan from the sound of it

anyway, just my .02 cents(.03 canadian) that you would be better building than buying

an appliance pc? Really?

I don't see why you would ever ditch your current setup for that prebuilt. Unless you run only single-threaded apps, you will be unpleasantly surprised with the PC you're looking at buying... the Core i5-650 is a dual-core, and the GeForce G310 is slow as all get-out.

Not to mention , if you stick to recommended mfr's, About the shortest component warranty will be 3 years (maybe 2 at worst) at no extra cost. If you really want it, you can add a year or two extended warranty to critical core components such as the motherboard, video cards and CPU. You can do this with Newegg for a fraction of the cost of an OEM or reseller. From what I have seen Newegg is much more reliable than most. Though with XFX video cards their double lifetime warranty is beyond reproach. Likewise your better memory suppliers.

DIY gets you exactly what you want with no "suitable substitutes" due to the advertised unit being "out of stock". You get full featured Bios with the mobo. And the list goes on.
