Is my gaming PC being significantly bottlenecked?

So I originally built this rig in the summer of 2010, but have slowly been trickling in a few upgrades over the years. I will be heading off to college this fall, so I'm trying to make sure this thing lasts at least another 4 years. Is anything in my system currently bottlenecking/will bottleneck soon? What's worth upgrading?

Current Specs:
CPU: Intel Core i5 750 (Lynnfield)
Motherboard: Gigabyte P55M-UD2
RAM: 4 x 2GB OCZ DDR3 1333MHz
PSU: 550W Antec
Case: COOLER MASTER Elite 341
GPU: 760 GTX 2GB GDDR5
Display: 1 x (1920 x 1080), 1 x (1680 x 1050)
Optical: Sony Optiarc Black 24x Dual Layer DVD
OS: Windows 7 Ultimate (I have no interest in Windows 8/8.1)
Storage 1 x 480GB SanDisk Extreme II SATA III SSD, 1 x 240GB Seagate 600 SATA III SSD, 1 x 1TB 7200 RPM SATA II HDD

I understand that my current mobo doesn't support SATA III nor PCI 3.0, though I've been told the real world gains for those with my SSD's and GPU aren't significant (I could be horribly wrong about that). I'm a bit bummed that I don't have any USB 3.0 ports, though are that and the CPU worth upgrading the mobo, possibly the case, and the CPU ? Any help, suggestions, or input would be greatly appreciated!

recent I5's are about twice as powerful, but unless your CPU is hitting 100% usage and holding you back, not worth changing.

PCIe3 and USB3 would be had with a new mobo, but you'd have to change your CPU then anyway. Both would be a good upgrade.

Do SATA III and PCI 3.0 offer significant real world improvements? Also, while I don't keep too close an eye on cpu usage, I have seen it spike to high 80ish percentiles. Any clue when Broadwell is coming out/worth a wait?
 
Don't upgrade your system right now. Wait for a while till broadwell is out. 97 chipset series mobos are already out. DDR4 RAMs are being rolled out.

It would be better for you to wait and then completely change the system rather than upgrading now just to realize that after couple of months altogether new tech is out which you could have waited and upgraded to.

Any guesses to when Broadwell will be out for desktops? I'll be heading off in late August and would prefer to build at home if at all possible
