I am building a new PC. In my country there is no price difference between i7-920 & Q9650. i am going to use this computer for gaming , Video Editing and Some sort of Multimedia Use...... for graphic card i am going with 5870HD and 9800gt or GTS 250 for physx.....
I am mainly confused in picking up the processor........... since both are quad core. i7-920 has base configuration of 2.66ghz which on turbo boost be reached at 2.93ghz nearly 3.0ghz(Q9650)..... Also there is option for overclocking..................
Plz Suggest me which 1 is better for long term usage??????
If you are building new system, and not trying to upgrade, then go with the i920-based system. It has an integrated memory controller and triple channel RAM. It may cost a little more for the board and the RAM than a 775-based system, but you'll have a modern, capable system.
The Core 2 Quad is dead technology. It's still a capable processor now, but the socket 775 motherboard it sits on is now obsolete and being phased out.
Get the i7 920 as that tech has a long life ahead of it.
I'm more than happy to suggest a spec for your video editing needs.
A note on your graphics setup: I don't know if the driver "issue" has been resolved, but you can't use a NVIDIA card for dedicated PhysX if you're using an AMD card for graphics - the NVIDIA driver blocks it.
The i7 is in blue on top. Higher or lower is listed in the benchmark column. i7 wins all but 4 and never gets left behind. But it does leave the 9650 in the dust on a number of other benches. If price is the same, go for the i7 920. The lead would be even bigger if you do OC!
