2500k build... kind of dissapointing - Page 4

post #31 of 43
It was a HUGE jump for my laptop. From 2 core AMD to SB. The best part about SB and ssd on a laptop is the lack of heat. You can actually use it in your lap.

If your CPU isn't bottlenecking your GPU[s] then why are you changing it?

Of course performance in games isn't going to increase if they are GPU dependent and not bottlenecked, if you had a CPU dependent game that was using 100% of your 1366 CPU, then the switch to sandybridge would be noticeable...

You didn't need it, no wonder your disappointed.

Why did I do it? It was a free swap to a year newer hardware... Oh and a pretty black mobo !

This is not what I'm seeing:
920@4.0 (HT off to compare apples to apples) 2xgtx480 840/2000-> 10100 3dmark11

2500k@4.8 2x gtx480 840/2000 -> 10300 3dmark11

same scores with a 20% faster cpu???

And for the SSD comments, you did notice my sig didn't you?

Anywho its no big loss, I'm sure some relative will want a new PC built this year

I wouldnt consider gaming benchmarks to be the end all and be all of comparisons. I would think any game that uses 4 cores or less (every game in the world at current id imagine) and is running some decent gfx power would run at least few fps higher on a 4.8 2500K vs a 4.0 i7 960. Your not gonna see much of a difference if you cards are already doing all they can though.

8x/8x vs 16x/16x is literally like 1-2% difference with any single GPU card on the market. If

well that's incredibly stupid

the i5 2500K is $179 at Microcenter compared to $199 for the 960 and decent 1155 boards are also significantly cheaper than decent 1366 boards, and if you really need extra bandwidth for your video cards (ie running more than two high end GPUs) there are always options like the P8P67 WS Revolution which is priced competitively with the good 1366 boards

you're not getting worse gaming performance, if it feels that way its placebo

the reason such a recommendation is so stupid is not just because its cheaper to go Sandy, its just better all around. Clock for clock SandBridge i5 is just as fast if not faster than 45nm Nehalem i7s in all but the most heavily threaded scenarios, and memory bandwidth has always been moot for single user scenarios except for in benchmarks.

Combine that with the fact that the i5 2500K can be far more easily overclocked (unlocked CPU, smaller die size = higher ultimate clock rate, and much much easier to control thermals) and I would feel sorry for anyone that listens to your recommendation to go with an i7 960 instead.

Completely agree with this ^^^^

This would be the difference in reduced latency of your PCIe lanes because of a lack of a northbridge...

Try a CPU bench, you will see a significant increase over you 1366 chip.

Same score. What am i missing here? You do realize that the cpu doesnt make much of a difference in 3dmark11 right? a quad is a quad. If you want to do a real apples to apples comparison, run your gpus in x8/x8 on your 1366 rig and run 3dmark 11. Your expecting huge difference in points because of cpu speed.

Post your gpu only score. From those two results i mean. Not the combined score.

^-- Yes, please post GPU score. Actually, please post all 3 scores from each system. The physics tests LOVE hyper-threading. If you're worried about benching, then you should have gotten a 2600K instead.

Just FYI...
- I've seen a 255 point graphics score increase when overclocking my 2600K from 3.5GHz to 4.8GHz.
- I've seen a stock 3.5GHz 2600K get the same physics score as a 4.8GHz 2500K.

Also, P67 8x8 is faster than X58 16x16. True story.
