Hi-I am in the process of upgrading my current desktop. My main conundrum is whether to upgrade my MB to a SLI capable board and add another GTX 660 or purchase a cheaper MB and throw in a GTX 770 (I know this question has been asked a lot but I was wondering if anyone had any issues with a similar build configuration)

I can get another 660 for $172 or a 770 for $334 (after rebate-would still need to dish out $450).

I have another separate build issue and that is whether or not to invest a little more and switch over to Intel (I am buying a new MB and my CPU isn't the greatest for gaming). My hesitation is that if I were to upgrade I would get a haswell CPU (4770K) but I am disappointed by the fact that Intel is going to change the socket when the re-release Haswell next year (as well as Broadwell), which really limits upgradability in the future.

Is this a valid concern? I know that you should buy and build for the present but it is a drawback when both the processor and motherboard that I will invest in now will not be backwards compatible in the near future

Looking for general upgrade advice but as I said my main issue is the SLI MB vs the video card and AMD vs Intel

My current Specs are:

Gigabyte M68MT S2P F1 (this has to go)

AMD Phenom II x6 1045T (would like to keep this CPU if I don't jump the AMD ship but I have to keep in mind the possibility of bottlenecking)

2x 4 gb 1066mhz Crosair DRR3 (will upgrade to 2x8..eventually)

Nvida GTX 660

1.5 TB 5400rpm HDD (will probably add a SSD and keeps this as a storage drive)

450 watt PSU ( this I will most likely have to upgrade)

I will eventually add a SSD plus some more RAM

On the AMD front I have been looking into the Gigabyte 990FXA-UD3 AMD990FX (but I need to look into the difference between UD3 vs. UD5, etc) and other SLI capable MB like ASUS sabertooth and even the crosshair V.

Haven't really started looking into Intel MB's yet
 
You definitely need to upgrade the PSU to something rated 600W or more, whether you get a single GTX 770 or a second GTX 660.

Two GTX 660 cards will beat a single GTX 770 occasionally, but not by much. Also, some games won't support SLI well. The single GTX 770 will make less noise and consume less power. Normally, I'd advise getting a single GTX 770 rather than two GTX 660. But, since you already have one GTX 660, it makes sense to add a second one. Maybe you can sell the GTX 660 and then buy the GTX 770?

The i7-4770k will be plenty for gaming for the next 5 years IMO. I just got one myself last month, and I don't care if Intel changes sockets :)

You should definitely get an SSD or a faster HDD for Windows and games. That 5400rpm is dragging things down. I've had one that could barely provide 60 MB/s. A decent SSD can do 500, and a Velociraptor 1TB about 210.
