Good friend of mine has a monster gaming PC which he uses to play Battlefield on. Which means that when I go over for a session, it usually lasts a while.
Intel i7-3820 3.60
Asus Sabertooth X79
Corsair Dominator Platinum 32GB's
ASUS GTX680
2 Corsair Force 240GB SSD's in RAID 0
4TB WD for storage
1350W Thermaltake power suppy
Thing is a monster.
The Raid 0 on those SSd's, for gaming, seems like a total waste of an SSD to me. I am 99.99% sure he would see no difference with only 1 of those SSD, and then having double storage on SSD's would be nicer imo!
BTW, I still use my 2500K stock and have been able to run things so smoothly with it. I even played BF4 beta with no lag. Got a GTX 570 and 16g of ram with it (8 would have been way enough, but it was so cheap and 1600 MHz too). I have absolutely no need for better rig since I play mostly at LOL.
Oh, and fastest computer? Well We have some decent servers at job, some Dell things doing the job way enough, but since we work a lot with databases, the CPU rarely work hard, even under big tasks since the disks are always the bottleneck. But 1 year ago we got to a point where we had some big problems when the SSIS (data importation) team was running big tasks that would consume all the I/O available and have a big impact on all the dev team. We were looking for ways to solve this, and considered buying another server or more disks, but after considering many costly options I suggested buying a single very high performance SSD (enterprise grade) that would be used for those massive queries and so we bough a intel 900 series SSD (the 800g version) and man does it deliver. That thing is plugged with a pci-express X8 and runs so fast that's amazing. I used it a little this last year for testing a job that is crunching 60 000 000 rows of audit and is then joining those rows with half the database and it was going at least 4 times faster than our better other disks option and it still had some juice available. ok, it was a 4500$ SSD, but worth every penny for us. And we still don't use more than like 10% of the server CPU most of the time.
