Have a choice of getting a new rig with an 8800GT today or waiting till the new nvidia 9 series(D9P) comes out in 6 months time.
Since the 9 series will be roughly double in power, i'm quite tempted to wait, especially if i can get the same rig a lot cheaper by then!
I agree it's all about timing, would it be wise to wait till June?
if computer sales is anything like other retailing, as well as the product cycles affecting 'best time tobuy' so will Christmas...as retailers might over stock.
I totally agree with spending money on those parts which last a long time..keyboard, mouse, screen, psu, case as the previous reply.
the other thing that significantly affects cost of upgrading is the motherboard..if it dont support the next gen cpu/memory it could be an expensive upgrade nest time around (new board + memory and even graphics..eg a year or so ago agp>pcie).
best value at the moment I think would be a very cheap core2 and p35 motherboard..(New sockets will be out q4 2008 i belive) so any board you buy now may well not have that long a 'life' when considering new cpus in 2009.
for the most part the last few % performance costs exponentially more money..dont go for more than you need in terms of performance...go for the platform / feature set you need.
nows as good a time to buy as your going to find.
common excess expeniture for value machine
>500w psu
fast timing / fast speed memory (PC-6400 is more than enough)
paying for a fast cpu/gpu when you dont game/video encode/ cad and other high performance activities.
if you are going for best value, and you dont have 'enthusiast' performace requirements then you might want to consider an off the shelf pc. Building your own tends to only be better value when you value more premium parts/features eg. quietness.
best bang for buck at the moment for games I would say is the cheapest system that has 8800GT 512MB (cheap oem) + cheap Core 2 2GHz + good cooler for maximum overclock + cheap p35 motherboard + cheap 2gb pc6400 (max) ram, 500gb hdd + an onsite warranty included.
