Real-time editing, bump mapping, static lights, network system, integrated physics system, shaders, shadows, and a dynamic music system are just some of the state of-the-art features that the CryENGINE offers. The game was set to Ultra quality and the Ubisoft's Regulator demo was run.

The performance difference here in FarCry is much closer, but realistically there is no way you could tell the difference between the 3 fps when gaming.

ID Software Doom 3 1.3	Source: id Software

Doom 3 takes advantage of the latest videocard technology and pushes the processing power of the CPU to its absolute limit. At its highest setting, Ultra quality, texture sizes pass the 500MB mark which means even tomorrow's videocards will have a hard time running everything. The frame rates in the game itself are locked at 60 fps so anything above that point is wasted. Each test is run three times with the third run being recorded.

Here in Doom 3 the difference between the Intel P35 Express chipset on DDR2 and DDR3 is about 10 fps.

ID Software Quake 4 1.3	Source: id Software

Quake 4 is the latest shooter from ID and is based on the Doom 3 engine. Tweaked to for more eye candy, Quake 4 promises to be tougher on videocards and systems than its predecessor was. Quake 4 also does not have a 60 fps limiter like Doom 3, with the Ultra setting, graphic textures can surpass the 500MB mark! Each test is run three times and with the third run being recorded.

The framerates in Quake 4 are closer than in Doom 3. If you want something that's a bit more future ready going with DDR3 may be the way to go, particularly if you plan on installing a quad-core CPU in the future.
