Im looking for a cheap used quad core proccesor for my optiplex 755. i just got a gtx 650 ti and i cant play games like bf4 while my brother with the same graphics card can. hes got a fx 6300 while i have a core 2 duo. im sure that a quad would make it "that" much more faster so if anyone knows a cheap one say under $30 used from a trusted site that would work in the dell optiplex 755 any reference would be appreciated.

Well, generally the problem with running a Dell is that they can put in some rather proprietary boards which may or may not support a beefier processor due to motherboard design (or lack of power delivery more likely). You could always try it - Q6700 is a quad core 3.0ghz which isn't bad, but to be honest, you're working with a SFF computer and they might have limited it to a dual core for a reason (psu/heat/etc).
Besides, modern platforms will easily outdo almost anything you'd put in there, meanwhile you could easily put the 650ti in a new computer and get quite a jump in overall performance for minimal costs. Right now you could get a Haswell i3 (make sure you get a hyperthreaded one)/H81 motherboard combo for about $150ish, get a case and PSU for it, swap over the graphics and HDD and it would wreck your Dell easily.
Normally I don't always advocate upgrading platforms as most fairly modern platforms (as in LGA 1156 systems and newer) don't benefit huge amounts from going from like an i5-2500k to an i5-4670k. However, your system really IS pretty obsolete. In your case you're far better off biting the bullet and getting a cheap Haswell setup (or Skylake)

I have the full tower version of the dell optiplex 755. i just put a 600 watt power supply to get this graphics card going. some games are alot faster than before and some are alot slower. so im assuming its the cpu. my guess is that if i get a quad of equal or more speed its bound to be faster than a dual core of the same make "core2duo-core2quad". i will look into the q6700 but i need to make sure the motherboard supports it? thx. o and if i get a new cpu it would be a fx-6300 and id get a new mobo and case at the same time. the black edition of fx-6300 is only around $100 and the mobo for it only around $50

Ah, well that's good news. If you have the full tower version of the system, then you can easily upgrade the motherboard and CPU. If you're going to do that though, I would honestly go with an i3 Haswell with a H81/B85 board. You can get the i3-4160 (2 core/4 thread) for about $120 and a Gigabyte B85M board for about $50 brand new (without shopping hard). I'm sure it could be found a bit cheaper.
And the i3 would beat the pants off the FX6300 in most workloads.

You can actually get a decent quad core for an Optiplex for rather cheap, though the original core 2 duo is usually 3.00GHz, and this one is only 2.5GHz, the cores are what would help:

and one particular graphics card that I found to work extremely well with my the Optiplex 755 is the NvIDIA GT 710. I received one as a gift, and its been in two of my major gaming computers. It works great for low power setups, and has no issues running even with the default CPU. Surprisingly powerful for the price.

A 650ti is far, far more powerful than a 710, which is only suitable for light gaming and an utterly terrible choice for a gaming rig. It's not even designed for gaming, it's a "I have a CPU without an integrated GPU and I need to be able to see things" CPU. It might not even be faster than his previous GPU - it's only a little faster than the HD 4670, a common entry-level GPU at the time this PC was new.

I never said it was a good choice, but for those of us with little money its practically the only choice, I have 2 710's in my current computer, along with the integrated equivelant of a GT 630
Its all about gaming on a low budget for some of us.
But whatever.
Fact is fact I guess.

He asked for help with his PC. You threw in an odd recommendation that he spend money to downgrade his GPU in addition to his CPU upgrade. Lots of people find threads on Google or searching the site, so it's problematic to leave strange advice unchallenged.

Well, since he's not running a small form factor system, and he's already jumped the PSU to aftermarket to handle the beefier card, he doesn't need to drop to a GT710 (that would be a big step down from the 650ti...). He needs more CPU grunt, and since he's not limited by a proprietary motherboard (full size desktops take standard mATX parts and aftermarket cards) he can pretty much put anything he wants in there.
Hence my suggestion for a Haswell i3 (2C/4T). Cost is nominal, and he's stepping up a LOT in capability.
