Is my system bottlenecking my graphic card?

System specs-
Antec 300 case
Antec BP550 Plus PSU
GA-MA785GM-US2H mobo
AMD 435 X3 @ 3.25ghz
2X2gb ddr2 @ 833mhz
Evga Gtx 460 gpu @ 850/1700/2100
WD 500gb 7200rpm hard drive 32mb cache

I'm asking this because when I run games like Crysis on high no AA I get 15-30 fps and get a lot of chugging frame rates in other games. If it is my system, would upgrading to a p67 mobo, i5-2500k, and 4gb of ddr3 1600mhz ram fix this?

As a side note, with the new power efficency of sandy bridge, would I be able to run gtx 460's SLI with my current power supply and the upgrades listed above?

Crysis is a very demanding game, even for the fastest systems with fastest GPUs....; if you lower the resolution and the framerate increases significantly, your GPU is the bottleneck. The 460 is a solid card, but, pushing it for Crysis unless below 1080P res...

a 550 watt PS would be pushing it for a pair of GTX460s....upgrade the PSU as well....

I oced my cpu (i5 750) from 2.8ghz with Turbo to 3.6ghz without.Crysis is now very smooth (30-40 fps ) on very high with my stock 5850.So are most of my games.
When I had it at sstock,I'd get 20-30 fps tops but it stuttered a lot.Now it doesn'stutter at all.You should oc that cpu if you want to have respectable framerates.

becoolbro,

Unless he has experience he may want to step down a bit on the overclocking too. I always suggest loading some kind of safe guard before you overclock so that you don't damage anything too.

Some food for thought!

If you run into heat issues on your CPU I would recommend jumping into the H50 or H70 from Corsair ($80-$100). Spend a few extra bucks, you will not regret it!

I run my Q9550 at 4.1 Ghz, idle it is around 30-35C, load around 40-48C. I have been running it for about 6 months now and alot of my friends have switched over to it... Great product and very easy to install.

^ h50 or h70 aren't bad coolers, but you can get better coolign on air for the same price... the corsairs are more imo for a quieter case with good cooling, true water coolign is much better than those close dloop main market systems

You do realize that 2.8 to 3.6 on an i5 750 is considered a mild oc...
I bet he can oc another 200-300mhz without risking anything.
