Assassins creed 2 and brotherhood slow running pc

[williamDull]

i bought the first game and the fps was like 1 so i double checked my requirements and found my graphics card didn't support pixel shader 3.0 so i bought a new one with great improvement but still slow in the cut scenes the words are off by about one second for a medium phrase if i am climbing a tower and look up i go faster look down and go slower when i get to an assassins tomb the screen goes black and a little note says driver failed and recovered i am not sure if it is the game, i did get the latest patch, my ram, or graphics card

graphics card
              - 8400gs nvidia geforce series 512mb
processor
              - AMD athol(TM) 64 x2 dual core processor 4000+ 2.10 ghz
Ram
              -2.00

I'm no expert when it comes to specs, but your CPU (processor) doesn't meet the minimum requirements, which I suspect may be a problem.

Your processor definitely needs an upgrade.

It seems like a problem i had with operation flashpoint dragon rising where menu text was gone(black) and the game was slow and laggish. id say download your graphic driver from the manufactor homepage then go get driver sweeper and clean out all graphic related stuff then reboot and reinstall graphic drivers works wonders each time i did it ^^.

any suggestions on what to get???

What is your motherboard make and model? It is AM2+/AM2 so it will support AM3 processors. AM3 boards are not backward compatible, though.
What's your budget?
I would be tempted to go for the Athlon II X4 645, but the price tag just drives me away...

No need to post this, it does not help in any way

I guess Vista is the culprit here.

You can ignore this post, as it has already been determined that the processor need upgrading. Guesswork does not help.
