General upgrade questions

  researcher 17:21 25 Mar 2007

Rather than buy another PC, I’m going to upgrade my current one.

PC: Evesham Axis 64 SLI, coming up got two years old
M’board Asus A8N SLI Deluxe
Memory: 2*512 PC3200(will upgrade: add 2*512 PC3200/PC4000)
Processor: AMD Athlon 64 3500/2200 core (will upgrade to: AMD Athlon 64*2 4600/2200)
Power Supply: Tagen TG420
Graphics: Dual 6600GT (upgrade to ??? see below)

Main use gaming and photo/video editing.

I know that I will need to update the M’board BIOS from 1005-003 to 1016 in order for the processor to be supported. Assuming that goes OK, (any tips would be appreciated!) then I’ll add the new Athlon and memory followed a month later by the graphics card(s)

So, a question: Will I need to upgrade my power supply and
Do I go for:
• Two Asus EN7600GT SILENT/2DHT 256M DDR3 / PCI-E / SLI / 2xDVI / TV-OUT in SLI configuration @ £216 total for two, or:
• One Inno3D GeForce 7950 GT 512MB GDDR3 / PCI-E / SLI / 2xDVI / TV-OUT @ £197, or:
• One Gainward GeForce 8800 GTS 640MB DDR3 / PCi-E / SLI / 2xDVI / TV-OUT @ £247

Many thanks

Go for the 8800 if you can afford it ....but your Power Supply: Tagen TG420 will probably need replacing as well.

Ooops just read the bottom ...yes get a biger power supply. I would sugest a min of 650w

Not sure about the best set up for the graphics. Have a look here and see if you can compare them yourself click here and click here whatever you decide to go for, I assume the power supply is a 420 watts amd if so can virtually guarantee it will need replaced to something with a higher rating.

Thanks for the responses and usefull links. Wikipedia also had some relevant info.

I'll upgrade the power supply (more money) but have another question. There is note of say ATX 12V 600w and ATX 600w (withouut the 12V prefix) power supplies, I assume that I go for the non 12V?

"There is note of say ATX 12V 600w and ATX 600w (withouut the 12V prefix) power supplies, I assume that I go for the non 12V?"
- All standard PC PSUs are of the 12V variety I think. Which two are you considering?

Instead of the extra 2*512Mb RAM, may I suggest a 1*1Gb module. This way you'll still have 1 RAM slot free if you ever feel the need to upgrade again. One thing to check though - the manual to see if the 3 modules will still run in dual-channel mode (my mobo, a Gigabyte, has 4 RAM slots with 3 filled: 1*1Gb & 2*256Mb arranged a certain way still runs in dual-channel mode).

How much are you getting the S939 AMD 4600+ for? It's a pity you can't use an AM2 equivalent as they're now only £71 (was ~£7 more a few days ago) click here. G

Crossbow 7,
no decision yet re power supply, but the cheapest reliable make. Either 600w or 650w.

The motherboard needs paired memory modules, I could go for 1*1GB but then it will not run in dual channel mode.

I'd need to swap the m'board to go for the AM2, this may be an option (and save flashing the BIOS) as the 939 AMD 4600 is around £130. But of course swapping the m'board brings other complications!

I'll mark this as resolved, but if anyone can add anything re the 12v power supply question that would be great.

Thank you all again.

The 12v is the main power for the motherboard.
