I can pretty much guarantee you that it will be faster with 4c/4t than with 2c/4t. I can run some tests at i7 920 clocks (I have a 965, but I can drop everything down to 920 level) in 15 or 20 mins though - what kind of 3d gaming and video encoding benchmarks were you thinking of?

I play Far Cry 2, Crysis, Mas Effect, Fallout 3.... games like that.
For the video encoding, .mpg to .avi ... flv. to avi. ... and other format conversions
I'm planning on upgrading. Is Core i5 750 worth the money? Tomshardware conducted a benchmark of a simualted Core i5 750 2.66 GHz (Core i7 920 2.66 GHz, HT disabled, one DDR3 memory channel removed). It totally beat the Phenom II X4 965BE 3.4 GHz
Here is my current setup
Intel Core 2 Quad Q6600 @ 2.4 GHz
Inno3D GeForce GTX 275 896MB OC Edition
Kingston 2GB DDR2 800 CL6
ECS GF7050VT-M5 (a crappy motherboard, no OC)
Samsung 250GB SATA
Samsung (SH-S202J) DVD drive
Samsung 2233SW 22" (1920 x 1080)
I can't use the full potential of my GeForce GTX 275 coz my Q6600 is slow... I can't OC my Q6600 since my motherboard offers no OC. If I will OC, I will need a P45 motherboard and a good CPU cooler.
Might as well buy a new CPU and motherboard
I saw a benchmark of a Lynnfield engineering sample clocked at 2.13 GHz with HT enabled. It was just overclocked to 2.66 GHz to measure its performance against Core i7 920 2.66 GHz. It performed very close to Core i7 920 and it beat Core 2 Quad Q9650 3.0 GHz
What do you guys suggest? Should I buy a Core i5 this September? Will Core i5 give a big performance boost over my current setup?
You can push your cpu with the ECS to about 2.8 ~ 3 Ghz and that will improve your gameplay since on a quad core the sweet spot is about 3.3Ghz (when it will saturate a high end GPU). So my answer will be: wait. Don't buy a new motherboard + CPU + memory just to get the same amount of FPS as you can get with your current setup if you overclock it a bit.
Vantage is far less CPU dependent than 06. If I posted 06 numbers, there would be a massive difference between the scores. Look at the CPU scores in Vantage if you want to see the largest difference. Windows Media Encoder shows a significant difference as well, but it only seems to use 4 threads, so it only gains from the clockspeed, not the additional threads (there's a HUGE difference between 4c/4t and 2c/4t on windows media encoder though).
Encoding/media editing generally like Multiple core + speed.
Most of the games arnt optimized for 8 thread. On OCforum a guy made test with few games and he had better FPS with 4/4 = less heat. He discovered that for the games he is playing, he is better without HT.
For encoding you say you are converting to avi which is just a container. I would guess you are probably converting to xvid which is the most common codec used for what are avi files. If that is what you are doing xvid doesn't even make full use of 2 cores.
I use my PC mostly for recording and editing HDTV and then convert to xvid for archiving. I tested 2cores vs 4 cores on my system and on a encode that took a little over an hour the difference was 13sec (2 cores was fastest) which is basically the same. Also my i7 is aprox 15~20% faster clock for clock than my wolfdale. Thee are times that 4 cores will help if you are doing other tasks that use a fair amount of cpu cycles but just doing the conversion 2 cores are as fast as more.
