It's impossible to tell what will be available by that time next year. By that point the Core 2 refresh may be out, as will Altair and Antares, whilst second gen DX10 cards may well be out. I would just consider what is the best value for your money at the time your ready to build your new machine (which as I I know well, is easier said than done )
Looking to replace my present PC next Fall. What cpu, MB, RAM,GPU, sound card andPSU should I be getting? I'll have a rather nice budget, as I am saving like mad...
