GTX460 SLI Bottlenecking?

[Killatackular]

Guys,

I have old rig the only thing I've kept up to date (somewhat) is the graphics cards. Current Specs:

AMD Athlon x2 5400 @2.93ghz
2gb OCZ DDR2 800
Gigabyte GA-m55sli-s4 mobo(was top of the line when new)
Sata disk drives.

Playin on a 24inch 1080p with graphic settings on high.

2x MSI GTX460 Hawks.
My question is after i added my second card for sli, i didnt see that much difference in FPS in gameplay, the avg frames i usally get in crysis 2 is about 55ish in sli, where before i was getting about the same. Is there any software out there that will tell me if my CPU is holding me back? I dont want to upgrade unless im going to see a big increase in frame rates.

Your cpu is a big bottleneck

look for a X4 cpu to drop in if you can

AMD Phenom II X4 960T goes for 125

Guys,
My current mobo is a old school AM2 socket, it dosent say am2+ or am3 or anything like that, what cpus will work in that slot.

You can't unlock the CPU on that motherboard (which is okay). A single GTX 460 would be HEAVILY bottlenecked by the CPU. I know because I had it and was bottlenecking a GTS 250.

According to Gigabyte's website, that board supports all AM3 CPUs: http://www.gigabyte.us/products/product-page.aspx?pid=2442#

Update the bios and then upgrade the CPU to a Phenom II x4 955BE or 965BE--whichever comes up on a better sale in the next few weeks. You shouldn't have to pay more than $115.
