I running a AMD Athlon 64 X2 6400+ its a moderate CPU you, can compare it to a Intel E6600/6700 dual core I think. I have the intention to do a Videocard upgrade, the cards I have selected are a HD4780 and a GTX9800+ based GPU, both from Gigabyte, see the link
Will I face some problems here, using these high performering Videocards on my moderate CPU???
Not at all. You're CPU is sufficiently high enough for these video cards. What are you currently running for a video card, and what games are you planning on playing with the new video card?

HD4870 is the superior card, and now that they are under $200 it is really a no-brainer. If you can spend a tad bit more get the HD4870 1GB. Extra memory buffer never hurts. I was a big Nvidia fan until the 4870 was released, and the Catalyst control has built in manual fan speed control for the card to make it run under the 70c-80c temps that it is usually at. With the fan at 30%, you cannot hear it and it keeps the overclocked GPU under 51c doing things in 2D and I bump it up to 40% or so during gaming to keep it under 60c.
Only fly sims, like Rise of Flight I'm using now a outdated Nvidia 7300LE 512Mb.
Have now only to determine which GPU is running better on this Rise of flight sim, Nvidia or ATI base GPU.
Flight simulator games tend to be more CPU dependent than GPU. On Toms gaming graphics chart Q3/2008, they use Flight Simulator X and the 9800 GTX, and GTX+ outscored the HD4870 in all resolutions. Since they are the same prince range, this is probably the one you'd want. Or you can get a Geforce GTS250 (just about the same thing as 9800GTX).
