Solve : Q8400 Bottleneck GTX 660?

Answer»

Hello guys ,

My system specs :-

Core 2 Quad Q8400 2.66GHZ
Trancend 2 GB RAM
Gigabyte G41 Mobo
Asus Direct Cu II GTX 660 OC Edition
500GB Seagate HDD
LG Cinema D2342 23" 3D Monitor

I recently upgraded from 9400gt to gtx 660...so the jump is TOO *censored* HIGH

I saw all the VIDEOS & even posted on this forum to get suggestion for 660

First game :- The witcher 2

I should be able to max out The witcher 2 with ubersampling off...but i am getting pretty laggy & low frame rates...so i turned down the shadows & still the same & even played with v sync On & off

GTA 4

Ok this game is a bad port & buggy as *censored* in terms of graphics & i've heard that it uses more CPU power than the GPU ...I get max 13 FPS & minimum 8 FPS

So a gtx 660 should be able to max out above games..i know the TITLES mentioned are graphic intensive games...i dont wish ultra settings on 660 but still at least playable framerates...

I wud have posted videos but with fraps these games become literally unplayable

Is this because of my Q8400...i searched the web & 60% of so called research says YES.. what do you guys THINK

I have a [email PROTECTED] and a 9800GT and I get 60fps in GTAIV.If you turn down the resolution, what happens to your frame rates?I turned down the reso to 1600X900 but still getting only 15-20 fps & some of the details to lowTurn the resolution way down, say to 1024x768, and see if it improves, that's the easiest way to check if you're CPU or GPU limited.Done but hardly 2-5 fps increaseI have played Witcher 2 on an Athlon II x4 620 2.6 Ghz with 3GB DDR2 800Mhz Corsair XMS2 ( 4GB limited to 3GB due to Windows 7 32-bit ) with 500GB SATA II drive and  ASUS ATI Radeon HD5450 video card with 512MB on 19" samsung flat screen with 1024x768 and I get between 20 and 30fps and details set to normal.

*The frame rate for me changed depending on how MUCH rendering was going on, such as if a lot of action is happening it slowed to around 20fps but if not much was happening it was like 30fps. * Its been a while since I have invested any money into a powerful video card mainly because I was getting upset with GPU cooling fan failures with the GeForce cards like the GeForce 8800GT from BFG. The fan stopped and the GPU melted down  and that card cost a pretty penny when I bought it new. I have since just bought $40 or cheaper video cards and currently use passive heatsink cards which I mount a 80mm fan towards them to keep them cool, and the games I run run fine on them including GTA IV and Driver - San Francisco. Driver - San Francisco actually causes my CPU fan to increase in speed to max when playing it and running from cops, so its CPU intensive. Witcher 2 and GTA IV dont cause the CPU fan to max out on speed.

The only thing I see is that your running on 2GB RAM, and I'd add more if the motherboard supports it, especially if your running a newer OS than Windows XP.

I have also seen degraded performance with single-channel memory config such as a single 2GB stick running worse than 2 x 1GB sticks in Dual-channel config.

Is your 2 GB RAM a single stick or a pair of 1GB sticks or a mix of 1GB stick + 2 x 512MB sticks as 3 sticks in 3 of 4 memory slots?
