Upgrade to 5870 bottleneck?

Hi
i was wondering if my current system would bottleneck a 5870 in games at 1680x1050 resolution?
Asus P5KPL/1600 G31/ICH7 Chipset with Pci Express 1.1 x16
Pentium Dual Core E5200 @ 3.6ghz

if it does is there any solution? also is my powersupply enough?
Xion 500w 17amp/18amp Dual 12v Rails
i currently run a 4850 just fine on it and i have some headrooms since my friend has a q9400 and a 4890 on the same powersupply as me but will it take a 5870?

Thanks in advance

Best solution

Yes, there will be a bottleneck. I'd recommend a $160 5770 for an OCed E5200 @ 3.6GHz.

Don't get a 5850 unless you plan to upgrade your CPU in the future.

A GTX460 for $200 is also a great choice, and performs better than the 5770.

but thats not enough graphics horsepower for my needs?, crysis should be playable @ 1680x1050 very high with a good 40+ fps(never dropping 40 fps even in intesse explosions etc) and i do plan on upgrading my cpu in the future, a cheap gtx 460 shouldn't logically be enough since its losing to a gtx 275 is some tests?

I would not call it a "bottleneck", that E5200 @ 3.6 is capable of pushing that 5870 just fine, it just won't push it as good as an E8400 or quad CPU would, the difference should not be that bad though.

I ran a 5870 on my E4500 clocked @ 3.3 and it ran fine, then i ran it on my Q6600 clocked at the same speed and the difference was a little better but not monumental.

If i were you though, i would get the 5870 only if i intended on getting a new CPU in the near future, otherwise, as BSD said, GTX 460 may be your best bet.

The GTX460 beats the GTX275. The GTX460 is slightly superior to the 5830, which is equal to the 4890/GTX275. And the GTX460 supports dx11, runs cooler, and scales better than the GTX275.

the gtx 465 is at the same price over here, but is it rly enough for my needs? i doubt it is

tnx, also i do plan on getting a new cpu in a few months, also will my psu be enough?

35 total amps on the 12v rails should be suffice to handle the 5870 as it calls for a minimum of a 500w PSU, might be pushing it close though, if you plan to upgrade the PSU, go with a corsair TX 650 or better to ensure quality in the future...

The card is overkill for your resolution except for Crysis and a couple of other games. If you have money to throw at a system like that then why not upgrade the CPU while you are at it ? Regarding what jonpaul37 posted well i just upgraded a E4600 and the differance is huge, and thats on a 4770. yes i did mean 4770.

okey, ill go for a GTX465 then seen some benchmarks and id say its a compeditor to a GTX285 by just having slightly less fps in most games(1-10 fps difference when the fps is above 100 doesn't madder at all, so id call them pretty much equal)

thanks for you help driving me to that choise, also now i can skip powersupply upgrade for now and do an upgrade to i3+GTX465 and then later throw in another GTX 465 with a corsair 650w later on.

thanks for everybodys help
