A good time to buy?

Hello all,

Just a quick question. My PC (Athlon 64 based!) is on its last legs now and I'm ready for an upgrade. I'm looking at an Athlon X4 of some nature, 4 gigs of ram, on board graphics or cheap card etc... Last PC has lasted me around 5 to 6 years with no upgrades, I expect the new one to do the same.

Use the P.C for browsing and movies / TV mostly, with the occasional bit of gaming (strategy usually)

My question is this; is it a good time to buy now? I see AMD have a new group of APU chips coming along for example. I've done a bit of reading around them, but haven't got a feel for if its going to be a major step forward.

As you can tell from my PC specs above, I'm not a hard core gamer, I'm never going to be spending huge amounts on graphics cards and the like, I'm just trying to make sure that I'm not making a mistake buying now rather than in 6 months. I'm familiar with the speed of advancement in computers, I'm just really trying to check that this new APU business ( or something similar) isn't about to make my purchase seem foolish.

Thanks very much for your time reading this.
