Hej Specialists at Tom`s

I have an old Intel i7 920 (2.66Ghz, 8mb cache) and my question is if it can work
together with the new GTX 780?

I have never overlocked before, but I might actually sit down and learn how to do it.

Computer speccs:

- Carbide 500R Case
- Intel i7 920 (2.66Ghz, 8mb Quad Core.)
- Corsair Hydro Series H60 CPU Cooler.
- 24GB Corsair Vengeance 1600mHz ram.
- Corsair 860 Watt Platinium Modular PSU
- ASRock x58 Extreme Motherboard - link to the old motherboard http://www.asrock.com/mb/Intel/X58%20Extreme/

If you guys say it is too old for the new GTX 780, I would consider upgrading to an i7-3770K CPU with the Z77 ASUS P8Z77-V DELUXE motherboard. http://www.asus.dk/Motherboards/Intel_Socket_1155/P8Z77V_DELUXE/

I have heard that the new Hashwell i7-4770K isn`t worth it because its only 8% faster.

What do you guys think? Can I still go with my old CPU and just upgrade to the new GTX 780?
 
Sure it will bottleneck , but yeah , I guess it wont bottleneck a lot. Not smart enough to buy a i7-3770K. First try the 780 on your current rig. If it doesn't work , buy a i5-3570K ( Great CPU ) and a Z77 motherboard if you feel to do so. Either way try the E3-Xeons. with Z77 Motherboards.
 
When the 600 and 7000 series cards first came out, review sites were still using X58 motherboards and processors (albeit 980s and 990s). If the game isn't too CPU-bound and you're running at resolutions 1080p or higher, you're still going to get good performance out of your i7-920. Unless you currently have a Titan or a GTX 690, you're going to realize a performance improvement on that architecture. As an example, I was able to run two 580s in SLI on an X58 architecture with an i7-960 and no overclock without experiencing any bottlenecks. The 780 offers performance around 5% better than 2 580s. See the charts and look at the difference between a GTX 590 (slightly lower performance than 2 580s), and the GTX 780:

A 780 would work fine on your current setup.

I have searched the net for comparisons between increased ghz in CPUs and the effect on the GPU performance.

What would the difference in performance be between an Intel i7 920 2,66Ghz, and an i7-3770K 3,5Ghz CPU when comparing to the gaming experience a GPU will give you? (in this case a GTX 780).

I have seen a lot of ppl who overlock their CPU`s but when it comes to gaming, I have heard that it really only depends on the GPU, and not so much the CPU? Correct me if i am wrong.
 


This must be assessed on the basis of each individual game. Most posters who harp on and on about "bottlenecking" have little to no knowledge about what they're talking about.

All games use the CPU to perform game logic calculations, and the GPU to construct the final visual scene. Everything else is a matter of developer preference.

Skyrim for example uses the CPU to perform some of the shadow and lighting operations that would normally be performed by the GPU. Skyrim is a game that is notoriously dependent on the CPU for performance and upgrading to a Ivybridge/Haswell processor may be a good idea if you happen to like lots of Skyrim mods.

Battlefield:Bad Company 2 and Battlefield 3 use the CPU to perform real time environmental sound processing (War Tapes audio mode) that has historically been offloaded to digital signal processors on Creative Labs sound cards. Enabling this can result in a noticeable drop in framerate if the CPU isn't up to snuff.

Many other games don't do any fancy processing and will simply have the CPU waiting for the GPU to do its job most of the time.
