1. What YOUR PC will be used for. That means what types of tasks you'll be performing.
I'm building 2 computers, one for myself & my partner for the purpose of web, email, voip & gaming as we both enjoy playing multiplayer fps and racing games

Games we would love to play are COD:MW2 & 3, Dirt 3, SC2, NFS (most current title), C&C 4 & BF:BC2. There could be others we wish to try out but we'll start with those for now

We might even join a F@H team too since us girls love helping out for the greater cause.
2. What YOUR budget is. A price range is acceptable as long as it's not more than a 20% spread
Around $3000 including taxes & shipping for both machines.
3. What country YOU will be buying YOUR parts from.
Canada
4. IF YOU have a brand preference. That means, are you an Intel-Fanboy, AMD-Fanboy, ATI-Fanboy, nVidia-Fanboy, Seagate-Fanboy, WD-Fanboy, etc, etc, etc, you get the picture.
Corsair, Intel, WD, nVidia (eVGA)
5. If YOU intend on using any of YOUR current parts, and if so, what those parts are.
No, all parts needed except for monitor, keyboard & mouse.
6. IF YOU have searched and/or read similar threads.
Yes.
7. IF YOU plan on overclocking or run the system at default speeds.
We are both open to exploring that avenue sometime.

Within a month
9. What resolution do you use?
1920 x1080 - Dell Ultrasharp U2311H, got it on special for $229
Here's a list of parts I've put together for you guys to review & make suggestions...
CASE: Silverstone TJ08B-E / Lian Li PC-A05FNB
PSU: Corsair TX650 V2
MOBO: Gigabyte GA-Z68MX-UD2H-B3 / Z68X-UD3H-B3
CPU: Intel Core i5-2500K
COOLER: Cooler Master V6GT
RAM: Corsair Vengeance Black or Blue 8GB (2x4GB) DDR3-1600MHz (colour dependent on mobo)
HDD: Western Digital Caviar Black 1TB SATA 3
GPU: eVGA GeForce GTX570 1280MB
OPT: LG GH24LS70 DVD Writer
OS: MS Win 7 Home Premium 64 bit OEM
Our wants for this build are to have front panel power & reset buttons with 1 or 2 USB3 ports (with an internal mobo connector - NOT pass through) on a small case that looks sleek & professional since we aren't into cases that look like alien space ships or the like

We love the look of Corsair's Obsidian line and also Silverstone & Lian Li's above mentioned cases if that gives you an idea of our preferred tastes.
We also want the mobo to have a USB3 header so we can use the said connector from the front of the case while also being able to have room for expansion cards like sound, tv tuner & maybe a 2nd graphics card too. I would love to get an ssd but my partner doesn't trust them so I was thinking of getting an OCZ Vertex 3 MAX IOPS 120GB SATA 3 drive and replacing the GTX570's with 560Ti's instead so it could be done within budget, but is it a fair trade off?
Finally, we would also like to ask if there is any particular brand of thermal compound that you all prefer to use or will any suffice for the job?
We look forward to seeing what you all think and what possible changes we could make to improve the performance
