Thanks for the input. Just a couple of questions though. Did you have two Opteron's in your system at the time?
I had two Opteron 6128s at the time, giving me a grand total of 16 cores at a maximum of 2.00 GHz. I was running eight 2 GB DDR3-1333 CL9 unbuffered ECC memory sticks at the time.
And even if so, does it really even matter when gaming? Or when gaming will i simply use only 1 CPU?
Having more than four cores is not terribly important for gaming at the present time. Look at the performance charts at the main part of the THG website. You see a big jump from two to four cores and then past four cores, little to no improvement. Once you have four or more cores, it really boils down to how fast each of the cores are. That's why the slightly higher-clocked quad-core i7s outrun the six-core i7s. If you have multiple 4+ core CPUs, only one CPU will really be used. Your games won't notice if a second one is installed or not.
Also, even if i were to upgrade my cpu, I would need to replace BOTH CPU's , which sounds rather expensive.
You do not need to replace both CPUs at once, but you will want to remove both old CPUs and only install the one new one if you do decide to upgrade one chip at a time. Many boards will not boot with two dissimilar CPUs. If it does boot, the faster CPU cripples itself to run identically to the slower one which you would not want to do.
You can boot and run just fine with one CPU. My current setup has only one CPU in a multiple socket board and it runs fine. You do just need to remember that you can't use all of your memory slots with only one CPU installed and you also may not be able to use all of your PCI Express slots either, depending on if you have two northbridges or only one. You would need to consult your manual for that particular information. My particular setup has two northbridges so half of my PCIe slots don't work with only one CPU installed, since there is no second CPU present to provide the HyperTransport link to the second northbridge. I can also only use the memory slots adjacent to the one populated socket. But other than those things not being active, it works perfectly.
And what kind of framerate cap are we talking about here?
Depends on the game and your GPU. I run Linux and games for it are not terribly graphically intensive. The toughest game I have played on the machine is Enemy Territory:Quake Wars and my GPU is an old GTS250. At 1920x1080 high quality, the 6128s pushed around 40 fps. The single 6234 averages around 65 fps with the same GPU and settings. Most of the games I play are much simpler such as the very fun but decidedly not very graphically intensive Cube 2: Sauerbraten. The 6128s would average around 170-180 fps at my larger monitor's full 2048x1152 resolution and the 6234 sits on the 200 fps cap all of the time unless a level is loading.
