Will these CP specs work fine for Blender ?

will these work fine for working in blendere without lag (also in Mudbox)

Note that if you want to use the cycles renderer, that graphics card will not give you GPU accelerated rendering

If you want to work with everything that Blender provides you must swap that AMD card for a Geforce. Also why do you want to get such an old CPU? You should look towards the AMD FX series if you do not want an intel CPU.

No matter what, artists will always push their machine to the max… so yes, after a bit of time you will experience lag with your machine, if you spend more money, this will give you more room to breathe, but then after a bit of time i am sure you will push that to the max aswell… there is no such thing as a lagfree machine built for 3d.

ok thanks guys !
