Baron Munchausen reminisced:
Good god... do you realize that I am reading this on an Asus A7V133 with a 1.2 Ghz Duron and a mere Matrox G450 video card? Yes, a six year old computer. It works fine.
Hah!
I'm making this post using a hundred-year old abacus, where you have to arrange the beads to form the ASCII values for each character - including the brackets for HTML tags.
(Disclaimer: Not really, using a 7-year old 1Ghz PIII laptop with a Geforge2Go 32MB graphics card - runs SEV OK generally though).
Fyron quoteth:
Isn't the only real difference between the geforce 7xxx line and 8xxx line DX10 support? Maybe some marginally faster speeds on various components? DX10 support matters naught if you don't upgrade to Vista, and is only relevant for 2 or 3 games so (including titles in the works).
The top end (8800) cards offer a more significant speed boost, comparable to a couple of 7800/7900's in SLI plus improvements to image quality (e.g. the ability to use High Dynamic Range lighting with anti-aliasing enabled which the 7xxx series can't do). Mid-range (8600/8400) cards apparently perform
worse than the previous generation though (as do their ATI equivalents) making the 7900/X1900 series the better choice for medium level systems.
However whether an upgrade is a good idea or not depends on what you are using your system for. If you have a large monitor for instance and want to run a graphically demanding game (e.g. Oblivion, Stalker) with good quality settings, then a graphics upgrade may be worthwhile - but for a future game, it would make more sense to wait until after it's launched (prices will be lower, more details on what the game needs will be available).
As for CPUs, a highly overclockable quad-core (e.g. G0 stepping of the Q6600) should provide more power in theory, but the reality will depend on what you run and how much concurrency you really need.
As for benchmarks, ones using the games you play are going to be the most important. There are synthetic benchmarks aplenty though (e.g.
Sandra,
3DMark) if you want to give those a spin...
