PCTech Forums

First, I want to introduce myself since I'm new to this forum. I'm just a regular PC gamer that knows a bit about technology and has built some PCs already. Now back to the question.
Recently, with my old PC slowly dying and new awesome games coming out(Battlefield 3), I've decided to sum up a couple of bucks and build my Gaming PC that will serve me without any upgrades for 2 years to come. Now these are my parts:
CPU: Intel i7 2600k
Motherboard: Asus P8P67 Pro
RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB)
GPU: Asus GeForce GTX 570
Storage: 2TB western digital 7200RPM black
Optical Drive: Samsung SH223
Case: Fractal Design R3
PSU: Corsair CMPSU-850HX 850 Watt
Microsoft Windows 7 Home Premium 64-bit

Now i have a couple of questions:
1. Are all those parts compatible with each other? I'm pretty sure they are but would like you guys to confirm that.
2. Will this machine be able to play all the upcoming games at full graphics with no lag?
3. Is it better to have one big hard drive (2TB), or two smaller ones (2 x 1TB). Are SSDs worth it?
Thank you guys for any help

And 1 more thing, I am planning to overclock the i7 2600k to around 4.5 Ghz.What custom AIR cooling would you recommend for cooling that? Up to 50 bucks.

Off the top of my head everything looks fine. You should have no issues playing all the latest games with all options turned on.

As for drives, there is very little gain in having seperate drives for a home system. So the choice is yours. It really depends on how you plan on storing things. As for SSD, the answer will depend on how much expendable cash you have to spend.

What made you pick that case? I'm not a big fan of front doors to my PCs. Just another thing to break IMO.
