E8400 Core 2 Duo bottleneck to a 7850?

Hi all, new to the forums (blah blah etc etc), need some advice as I've not updated my PC for 4 years :eek: yes I know I'm rubbish!

Anyway I'm in the process of ordering a 7850 as my 9600GT is dying a death and I'm wondering what sort of (presumably) massive bottleneck I'm to expect with my weakling E8400?

I do plan on upgrading both mobo (currently a gigabyte ga-p35-ds3p) and CPU later in the year but I'll have to live with the above combo for 6 months at least, if it is a massive bottle with a rather large neck then I might bite the bullet and upgrade my CPU (keep current mobo) sooner and have done with that....which will lead me onto a follow up question later no doubt!

ta for any help :)

If you have that e8400 overclocked then it should be okay for most games.

You should be able to get close to 4.0ghz with ease.

its not overclocked, that is a further option I guess.

Sorry forgot to mention the only games I'll be playing are FIFA12, SW:TOR and Rfactor2....maybe BF3 just for a look as I cant run it now!
 
There will be a bottleneck, but if your upgrading the CPU in 6 months don't worry. My E8400 @ 4Ghz bottlenecked my HD 5870.

Post some benchmarks, it would be interesting to see the impact the E8400 has on a HD 7850. :)
 
I have an e8500 clocked to 4ghz and I get 1100 on Unengine

which is nealy double what I used to get with my 4870 but it is about 300 less than somoene with a 2500k clocked to 4 so its not too shabby but new cpu's are the way to go

If you can get a q9550.

I have a q9550 @ 3.59 due to my p35 motherboard and it has enough power to play games above 40-50 easy or 60 or a bit higher varying with game.

A 6950 or 7850 will be bottlenecked very little by the cpu.

As with other people it would be better to get a whole system upgrade.
 
thanks very much all, cash is the problem right now and really want a decent GPU instead of just getting a low end one. I have checked out the possible CPU upgrades for my mobo so that is another option, I'll order the 7850 tomorrow and just see what its like. If the bottle neck is to much then I may have to save a bit quicker or look into overclocking my current CPU for the time being.

thanks again for the great help, much appreciated :)
 
Id love to get my q9550 at 4ghz, but could only manage 3.6 without having to mess around with the fine tune PLL, VTT settings which made no sense to me what so ever and kept crashing in Prime.
