I recently upgraded my MB to accommodate Core i7 CPU and 16.0GB RAM.
I am currently running a single GTX 550 Ti 1GB GPU and I was considering upgrading that piece as well. Would it be more advantageous to purchase another 550 Ti for SLI or just upgrading to the 650 or 660? The 650 is about $30 cheaper than the 550 Ti, but the 660 seems to be anywhere from $80-$150 more expensive than a 550 Ti. The other thing is my PSU is 700W and I'm not sure if it would support the SLI. If it wouldn't and that means upgrading the PSU as well, then I assume the SLI option becomes unnecessarily expensive.
 
If your motherboard supports SLI I would buy another 550ti, or if it doesn't (or you don't wanna go for SLI) I would sell the 550ti and maybe get something like a 7850 2gb or 7870...I'm not an expert but I believe 550tis in SLI would beat a single 650/650ti and the 660 although you might run into trouble in some games if you use SLI because as amazing as it is it's not perfect :D

I'm sure it does. I know enough to put a computer together and understand most compatibility issues, but as far as performance and SLI GPUs, I'm quite ignorant. I wasn't actually planning on SLI with the 650 or 660. I already have a 550 Ti, so SLI just means getting another card. Getting two cards right now is not really in my budget. So I'm trying to compare SLI 550 Ti vs. one 650 or one 660.

Here are my specs:
MB: GIGABYTE GA-Z77X-D3H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel
CPU: Intel Core i7-3770 Ivy Bridge 3.4GHz (3.9GHz Turbo) LGA 1155 77W Quad-Core
RAM: G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600
GPU: EVGA GeForce GTX 550 Ti (not sure if I have 1556 FPB or 1557 superclocked) 1GB 192-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI
PSU: I don't have the exact specs, but I know it's 700W, 12V and I'm pretty sure it's OCZ but I'm not entirely sure. I'll have to check once I can get back home and look inside.
 
Excellent. The more I think about it, I'm almost certain it's OCZ. Okay great, thank you very much, gentlemen. I appreciate it. Quick bonus question: what is the process for switching my display from my HD monitor to my HDTV, and in doing so, do visuals when gaming become laggy at all or are there any issues related to using HDTV for your display?

Just swap the cable and as long as they are the same resolution your good.you can probably hook both cables and use the control panel to switch, or just have both monitors on with a mirror display then just change the tv's input when you want to see the computer
