Hi all,

I currently have an Intel C2D E6750 CPU overclocked to 3.2ghz. I also have a HD4870 (stock settings). With this setup, is my CPU bottlenecking my performance, or is it sufficient?

Also, my g/f's machine is an AMD 5200+ running at stock speed (2.6ghz). She has a 4850. I have a feeling here CPU *is* bottlenecking her system. Am I right?

First things first... Your GF has an awesome gaming rig?? :D :D :D My gf won't even let me spend money on a gaming rig :( LoL!!

Likely, her processor is bottlenecking. Check the results (actual game play etc).
Probably the same for your PC, since your processor is running quite fast.

Thanks for the reply sn3rd. Yes, her rig is used for gaming, but she's having some performance issues with Warhammer online. Her system's laggy during PvP scenarios even though she has all her gfx settings on minimum. I'm thinking that a 4850 should be more than sufficient for Warhammer to run smoothly on high, so it's likely the CPU.

When you say this:

do you mean that my CPU is probably also a bottleneck?
 
What resolutions are you running at as any core2 over 3gig should not be a bottleneck until you hit sli or cf.

Even the AMD cpu should handle fine, what is the rest of the systems specs ?
 
Both machines are running at 1680 x 1050 rez.

g/f's machine has 4 gig RAM, and is running on Vita Ultimate. Can't recall what mobo she has.
 
SuperPI her!

Or let me be more specific. Run superPi with 1million iterations on both. This'll give you an idea how the processors compare

Then Grab Prime95 and run each of the individual tests and compare these to yours. There's Mixed,Memory intensive and Processor intensive

This'll give you an indication where there may be something funny if processor or memory is the issue
 
SuperPi will obviously be faster on the Intel system and proves nothing and as for Prime what is the point of checking for stability when both systems are stock and he is asking about bottlenecking.

At that resolution i doubt you will have bottlenecking as the gpu is doing the most of the work then.

Anyway my 2 cents :)
 
Thanks again guys.

So, if it's unlikely that there's bottlenecking on the g/f's machine, any other suggestions on why she's struggling with WAR on all lowest settings despite having a 4850?

(please excuse all the noobish questions).
 
could be power supply not up to the 4850's needs, have not played war so no idea of its needs. Possibly internet prob (i do not play online games so no idea of the terminology)

Can't be an Internet prob, as we share the same line at home.

PSU maybe, as she has a crappy no-name 550W unit.
 
If yours is a better quality one why not try swapping them and see if the same slow downs happens.

Also check cpu and gpu temps as they could be throttling due to heat.

Wow, hope you gave your balls an extra hug goodbye before you cut them off and set them adrift on that burning raft! ;) Bt seriously, that is just absolutely sad if you're not joking, which I hope you are!

It isn't about who's faster or who not,but one would think a 100% difference might be indicative of something far more sinister than a standard Intel/AMD QQ fest

If the prime tests act fuzzy on memory bandwidth for one and not the other then a culprit was discovered etc. These tests are meant to stress systems that are not graphics related to take graphics out of the equation. If all's fine then graphics gets blamed and we move from there

You can have the 2c's back now :)

Ah, that makes sense actually, will try that tonight, thanks!

lol what no interest :p
 
I have a AM2 5200+ with 2GB Ram.
I have the ATI Radeon 3870.

I play Crysis and Crysis Warheads on it at x8(AA) and all graphics settings set to its max.
My CPU doesn't even go to 50% and I use around 1GB ram, my graphics card is not overworked even though the game is massive and demands allot. The game runs smooth and only time the image freezes (slightly - longest time 2 secs) is as a level starts or when graphics settings are changed.

The above said I don't think the problem is the CPU or the Graphics Card I think it might be the PSU that it not able to supply the graphics card and PC with enough juice when needed resulting in bad performance.
Try running the game at around 800x600.

One thing I will say though: The CPU Sucks with Desktop applications but is brilliant with games.
 
Alright, ran Super Pi on both machines. My machine does 21 iterations to 4M in 1min 29 secs. g/f's did the same in 2min 55 secs. Seems to be a prob with her cpu then?

well, that cpu seems rather slow...

Hmmm, cheap for background applications, and app's that are in the task bar... those might be sucking the juice from the cpu, so when games come along, there's no power...

I doubt it's her PSU, 550watts is enough, well, I bet a 450 watts will suffice...

But try this, press Ctrl+alt+delete to bring up task manager... then click on performance and look at the cpu load and the ram used...

Another quick fix is to increase the virtual ram... this worked for me with hitman-blood money...

wtf!? how is an AMD hd3870 able to run crysis with 8xAA and max settings??????? that's one insane card then! I call you a liar! (unless you run it at like 640x480 :D)
