Worth upgrading LGA775 CPU?

Hey folks,

I'm looking into the idea of upgrading the CPU in my system to get another year of decent-ish gaming out of it. What I'm wondering is: Will I actually get a significant FPS increase from only a CPU swap?

Current system:
Intel e2180 CPU @ 2.4 GHz
ASUS P5N-D board
2x 2GB DDR2 800MHz
AMD Radeon HD 7770
Single monitor at 1920x1080
Windows 7-64

I currently get 10-30 FPS in congested areas on WoW/SWTOR and would like to try GW2 which is supposedly a little harder on the system than WoW. It's playable but kind of annoying. My goal is to bump that 10-30 up to more like 20-50 or 30-60 just to smooth things out. I assume I'm CPU-bound because I'm getting the same FPS with the new 7770 as I got with my old nVidia 9800GT...

I'm looking at either upgrading from the E2180 to either an E8400 or a Q9550 (running either with small overclock, 300MHz or so). Anyone have an idea whether I'll see a substantial FPS increase swapping to either of those and if so how much better the Q9550 would be than the E8400? It costs like $120-150 versus $40-50, pretty big difference.

I plan to build a whole new machine in 12-18 months so don't really want to spend money on anything else beyond a CPU for this machine - it will be demoted to file server status at that time and any upgrades will become a waste. Thanks!

Based on your testing, the solution seems pretty clear! There's really no arguing with those results, CPU is clearly determining performance there. And a 66% clock speed increase producing an 80% performance increase is nuts. So maybe grabbing the E8400 is your best choice. It's clock speed that the game seems to...

i am sorry buddy but yes..i was like you and now i am suffering so don't go with a cheap CPU..i have a phenom x3 8650 2.3ghz and i got ati 7770 same as you and it works on 20% of power :l

Actually try going to MicroCenter near you or search their homepage they got all the old CPU's for very low prices :p

Core 2's aren't dinosaurs bud. With that said you can go to ebay and search.

You've got one of the slowest core 775 processors Intel made. You can get a much faster one from ebay. Q6600 was very popular a very overclockable. I use a QX8650 from ebay and it ranks only 2 tiers below the modern cpus and up there with the first generation i5 and i7s.

You could still get plenty of use from your old PC if you get a good replacement cpu. Add some ram and an ssd and it would be pretty good.

what i said was about their production they do not produce them as much as i know why produce a Q9xxx while you can get best of it and more from i3? :D
 
They're not Nehalem/Whatever Bridge fast, but they're certainly not terrible. I used to use a Q6600 and it served me well. There wouldn't be much benefit upgrading to a dual core though, best to maximise your platform and go quad core. That being said, you're after double/triple your current framerates and I doubt a CPU upgrade will be able to deliver that.

This is the main question. I'm not exactly looking for double/triple the FPS so much as bumping up the minimum from 10-15 to 25-30, avoiding those nasty slowdowns. It looks like other people with 7770's are seeing 30+ minimum fps so it is a question of whether the E8400 or Q9550 would be sufficient to shift the bottleneck back to the GPU.
 


That would be a doubling (or slightly more infact) though of your minimum framerate. Although the absolute gain seems low, the relative gain is pretty big. I think it's unlikely a CPU upgrade could deliver that. Bear in mind also that the 7770 is only a little faster than the old 4870s, and a 4870 coupled with an old Core 2 Duo/Quad processor certainly wasn't considered a bottleneck.

FWIW I just started experimenting and I'm running at 100% CPU usage sitting in Stormwind. Overclocking the 7770 does not change the minimum framerate at all.

CPU at stock 2.0 GHz minimum framerate = 10 fps

CPU overclocked to 3.33 GHz minimum = 18 fps, still at 100% CPU, OC on the 7770 still has no effect

I think if I can get up to near 20 on this processor, perhaps 25 or 30 is not unreasonable for the E8400 or Q9550?
 
For the amount of money that you would have to put into the CPU you would be better off making the lunge into a i3/i5 system or like others have suggested a10 platform if you are on a budget. the q9550 is quite expensive online and the e8400 is still a dual core and you will want a quad if you plan to upgrade with the price of a q9500

Versus the q9550 for 10 dollars more then all of that :p

It's clock speed that the game seems to be craving and the E8400 is 3GHz stock.

I'm inclined to agree with bigshootr8 about the Q9500 - I'd feel like I was being ripped off at that price for a processor that was replaced over four years ago. It's not your retailer, it's just unfortunately what you pay for these where you can still find them.

Ended up grabbing an E8400 for $45 shipped, I'll give it a shot and if it isn't enough I'll just resell it and switch over to an i3-3220 or something. I'll report back with results when it arrives for anyone who might be curious.

Update: Mission accomplished.

E8400 @ 4.0GHz + 7770 @ 1100/1250MHz clock/memory = 85% CPU usage, 100% GPU usage with 25+ FPS in Stormwind on max settings (ultra, 8x AA) at 1920x1080.

CPU swap pretty much doubled the minimum framerate, the E8400 also runs much cooler. E2180 took 1.5 vcore for 3.0GHz, the E8400 is at 1.26 for 4.0GHz!

Now I feel like I should upgrade the GPU! :lol:
