Gtx 460 bottleneck

i was noticing that buying a gtx 460 and replacing my old gts 250 wasn't a smart move. this is because im running on a E5400 at 3.2ghz.
so...

i have 2 options

1) buy a quad core cpu, ive been able to find a Q6600 for $200 (Australian $$$) or i could get a Q9400 but i will need to get a new mobo since the Q9*** and Q8*** weren't meant to run on g31 chipset mobos

2) stay with my E5400 for as long as possible (max 1 year) and save up for a new PC (i might even get my first AMD PC...)

b4 i forget, my PC specs

e5400 OC'd to 3.25Ghz
MSI G31M3 Mobo
GTX 460 Gigabyte OC to 750/1500/2000
4 GB ddr2 ram
550 watt great wall power supply
Win XP pro SP3 AND Win 7 pro 64 bit (dual OS)
19" LCD at 1440X900
playing games such as GTA4, Mafia 2, Last Remnant, and more games when they come out. (cant wait for dead rising 2!!!)

At 3.25GHz, you should be fine for the time being. Going to a Q6600 or Q9xxx from an e5400 wouldn't be too ideal since it'll be much better to just so straight to a p55/x58 chipset. You will, however, continue to have issues with games like GTA4, which seems to rely on a sturdy CPU. But for the most part, most games will not have trouble with a CPU bottleneck with your e5400@3.25GHz.

Push your gpu to 820-840.
See if that helps in games, if it does, your cpu bottleneck is not that bad :) 
I have the gtx 460 also , and from all the reviews and stock models that come at 810, you can push your o/c some more.

GTA4 is poorly coded and is a RAM, CPU, and VRAM black hole.

You need a very fast dual core or a quad core to get decent framerates.

If you can get a 775-quad for cheap, go for it. Otherwise, overclock your E5400 to 3.6GHz+ and save up for another socket build.

The E5x00 overclocks great, and I got my E5300 to 3.6GHz on 1.31v and a crappy $10 air cooler (30'C idle/52'C load), so you should be able to hit 3.8Ghz-4.0Ghz no problem with a small voltage increase.

(a reply to Bluescreendeath as well)
well id like to but then the temps, noise goes up and the lifespan goes down so ill keep my clock speeds where it is, also overclocking only goes so far so its not worth it.

just save your money and buy the new sandy bridge cpus which is to come out by q2011.

And could you post me your 12v amps of the power supply?

Temps will go up, of course, but as long as it's under 90-95C, it should simply be an afterthought.
Noise will be louder, but GTX 460s are known for being the quiet GPU of the GTX 400 series bunch. It should be one of your least worries.
A lifespan issue should be a non-factor. Considering that you'll be upgrading within 2-4 years anyway, the card will be completely fine for that term and much longer afterward even with an extensive overclock.
Overclocking is completely worth it, especially on a GTX 460.

Save the money. The Q6600 was a great CPU, but for $200 that's about what you can buy an i5-750/760 CPU for. That of course would require new RAM and a P55 motherboard. Point being though, the Q6600 is more expensive than it really should be (prices seem to go up when they fade out of use).

As was mentioned, GTA IV is a HOG! It's quite demanding (even when it should not be). Also, at 1440x900 your GTX 460 should do FANTASTIC with any game you play. Play with your graphic settings a bit. If you can increase graphics quality without losing FPS then keep doing so.

To get your money's worth out of the new GTX 460, honestly the $200 you plan to spend on a Q6600 should be used for a better monitor. :)  The CPU becomes less of a limitation as your resolution increases. So whether you play @ 1920x1080, 1680x1050, or 1440x900 the CPU should be doing the exact same workload. However, the higher the resolution, the better the image quality, and the more use you get out of that GTX 460.

Games like Mafia 2 however, would strain the GTX 460 if you're using high settings.
