As previously the Intel Core 2 Extreme QX6700 comes clocked at 2.66GHz and it's performance is impressive to say the least, but that doesn't mean you can't get more out of it.

I remember having this beast CPU back in late 2006 when they first came out. They were insane for their day and with my EVGA 680i SLI board, SLI XFX 8800 GTX, 4GB of Mushkin Redline XP2 1000 (was among fastest RAM back then) and I had that sweet build inside a Cooler Master Stacker 832 Nvidia Edition. All of his was connected to an Enermax Galaxy 1000W PSU along with an Agia PhysX 128mb card before they became standard inside modern Nvidia GPU's. I also had a 30" Dell 1600p monitor too along with a Logitech G15 Blue version and a wired G5 mouse because I hate swapping batteries and such, wired has less chance of interference compared to the wireless ones and response times is vital for my PC gaming, lol. My rig at the time spent the first 3 months after launch with air cooling when I had a Zalman CNPS9700 before fabricating my own WC kit for both the GPU's and the CPU. Then I was able to easily push my CPU above 3.6GHZ+ stable and decent temps too once it was WC'ed. I remember spending about 6K+, but that put me in a large debt that took me 5 years to pay off.. Lesson learned, work hard for for your want and get your things within your means too and with the correct research, you can build a beast for cheaper, lol. I sure did had among the fastest 1000 or even in the tens in world wide rankings with my 3.4GHZ+ OC right off the bat on day one, lol, It was one of the few beast in the world at the time that could play Crysis on High settings, lol. My PC was the envy of every gamer on campus and I used to charge them to play by the hour, I made a decent amount of bread to upgrade to the first generation SSD's and such, lol. It was such a fine beast that I continued to use it until the X58 platform came out as my main gaming rig, it then became a guest rig at my own home after my days in college and I made a decent profit when I sold it, I made over $1K when the rig was nearly 5 years old. It was also fun messing around with the multipliers, FSB and the PCI-E lanes along with RAM timings and such, man those were the days before the simpler elegant BIOS GUI's and features we have today. I do admit, I was a wire management noob back then too, thankfully I was careful enough to install and seat the CPU and such correctly as I had flawless gaming performance for years since I also had 2 300GB Raptors in RAID 0 for games like Crysis, Oblivion with hundreds of mods and the early ENBs too. and the Half Life series along with one of my all time favorite games in Garry's Mod. It's pretty impressive that the eight year old QX6700 still holds it's own for midrange to high end gaming you you add things like SSD, more RAM and a GTX 970/R9 290 and game on a 1440p monitor or better will give new life to last another 5 years or so, lol.
