Oh by the way:

it will be used for games on a monitor with a max resolution of 1920*1080

Depends on the games you play. At the moment as I understand it CPU speed is the most important factor after having two cores.
Overclocking your cpu would help but would probably require an aftermarket heatsink/cooler.
But I'm not that familar with games.
The X3 is worth trying first unless you plan future upgrades.
I believe at this time either the Athlon II X4 or the Phenom II 955 offers all you would need.

The x3 435 will NOT bottleneck a 6850 or any other single graphics card.

No problem ....




With an 890FX and DDR3 1333 you can run 14x250MHz at 1.375v with the IMC/NB at 2500MHz and 1.2v or less . That should give you an easy 15-20% on your frame rates. Your biggest problem is your power supply (assuming you are going with the HD6950 2GB):



Use 150w for the remaining system load (OC'ed)



edit --- I'm now firmly on the fence :lol:  I think you can use your PSU and go with the HD69502GB but ...

Using PowerTune you will need to find a 'sweet spot' somewhere between 210-230w for your video card. You will most likely need a new PSU when you flash that second BIOS to a 6970 and boost the the volts a bit.

A new PSU would also give you some room for 14.5x250MHz at 1.4v.
