Suggestions for upgrades please keeping the current motherboard, this is mainly used for gaming (BF2142 far too much), and the occasional bit of video processing.
I'm certainly considering upping the ram to 4GB by adding another 2GB of the (TwinX2048-3200C2)
I know about the problems with this board accepting the 2GB at full speed, and XP only using a max of 3GB. :-(
Open to suggestions on processor, what processors are there out there left for the 939 than won't cost me an arm and a leg but will give me a leg up with performance.
Graphics card as well..suggestions please.
ASUS A8N SLI Premium
Athlon 64 4000+ (San Diego)
2 GB Corsair Ram(TwinX2048-3200C2)
EVGA Nvidia 7800GT
Viewsonic VP930b 19" Flat Panel
Maxtor 500GB SATA II 16MB Cache
Seagate 250GB Sata II 8MB Cache
2 Pioneer DVR-110BK DVD Rewriters
ThermalTake Tsunami Case
Seasonic S12 Power Supply
Since your current chip is 2.4G and 2.2G seems to be the highest 939 X-2 clock available I wouldn't expect a chip upgrade to make a huge difference in performance. That being said, I'd still probably do it since an X2-4200+ is cheaper, probably uses less power, and the second core will be generally useful.
Investing in DDR memory when you already have 2G doesn't make sense, very few games would benefit at this time.
Graphics cards are where the big payoff is in games. Of course they're also the most expensive item on your list.
My 2 cents is think of the future.
More memory is a waste because sooner or later you'll upgrade to a system with DDR2 or 3.
As for a CPU the Athlon X2 4200 for the 939 is only 69.99 but if you look at Toms CPU charts for 2006 its not much of an increase about 5 F.P.S. in the games I looked at. Of course you have two cores then. The Opty is just too much money for a CPU that won't keep you happy till next year.
To me the only thing that makes sense is to buy the very best video card you can. A Nvidia 8800GTX or ATI 2900XT. Something you can put in the next machine you build. Your current 4000 won't be able to take advantage of the power these cards have but it will scream in the next one. On the downside you may need to up your power supply too, but that will power your next build too.
Well the fastest dual core 939 processor amd made was the Athlon 64 X2 4800+ 2400MHz, 1000 MHz Hypertransport, 110 W TDP (damn thats hot), released on May 31, 2005 part number ADA4800DAA6CD (Toledo E6 90nm core).
I would say get a 8800 GTS/GTX series video card tho that would be the only way to increase your gaming goodness in a way you will notice. Also, you can bring this upgrade to your next computer. Just make sure your PSU is up to the task aka and can do 12V current at 34A for the GTX and 28A or more for the GTS. You can add the 12V rails together, this isnt necessary on a single 12v rail.
You could also OC a bit, im sure your corsair ram has some power in it then just pc3200. Dont be afraid of cas3 if you can get that ram speed up, just run those benchmarks and compare.
Your rig was clearly made of good parts in its day but you are ready for the big upgrade now. Your rig is not too old to sell still. You could get some $$$ cash back to put towards your new rig. Your old rig would make a budget gamer happy. If you are light on the funds then the best video card you can afford is going to help you the most, like a 8800GTS 320.
