Hello,
I would like to help my son to upgrade his system on a small budget:

He would like to achieve better graphics performance (resolution, more fluent game)

Main use: 2nd tier games (not the very latest stuff)

System: GT7600 Asus V2M, Athlone 64 3800+, 1 GB DDR2-800, XP64, 420WPSU, Monitor:1680

Question: What is the most effective upgrade?

1. Are these VGAs okay to consider? -> HD6670/HD6770/others?
2. is spending any more wasted? i.e HD6850/HD6870?
3. What does a RAM-upgrade do? 1GB->2GB/4GB
4. Does the PSU need to be upgraded too?
5. He can get a HD5630 for very little money should he take it or is it or close to the current VGA?

Thanks for any suggestions
 
The Radeon HD 5670 or HD 6670 would probably be the most I would upgrade to. The Athlon 64 3800+ is a single core CPU and will most likely bottleneck a faster card.

Additionally, the motherboard is a bit old and assuming it has a PCI-e 1.0 slot, it will have no issues with a PCI-e 2.0 card. However, it some old motherboards with a PCI-e 1.0 slot can be incompatible with PCI-e 2.1 cards.

There is a possibility that you may have a motherboard with the now obsolete AGP slot. Therefore, you need to find out exactly which version of the GeForce 7600 GT you have because PCI-e and AGP are not compatible with each other.

Assuming you have a PCI-e 1.0 slot, then the safe bet would be to buy a PCI-e 2.0 Radeon HD 5670 for $63 after rebate.

If you want to take the risk that a PCI-e 2.1 card may not be compatible with your motherboard, then you can buy a Radeon HD 6670 for $65 after rebate. It is about 10% faster than the HD 5670.

If you have an AGP slot on the motherboards, then the best card you can buy is the Radeon HD 4670 for $99 after rebate. It is approximately 25% slower than the Radeon HD 5670.

If $99 is too much money, then you can buy the slower Radeon HD 4650 for $80. It is about 25% - 30% slower than the Radeon HD 4670.

Thanks very much,

You are right - the board has got a PCI-E 16 v1.0

Any thoughts on the benefit of more RAM with the above VGA cards?
 
You should upgrade to at least 2GB of RAM. Upgrading to 4GB would be better since some games can use as much as 1.6GB of RAM after a while because of memory leaks. Which leaves very little for the operating system. However, if you have a 32-bit operation system like Win XP or 32-bit versions of Win Vista or Win 7, then the operating system will only recognize around 3.25GB - 3.5GB of RAM.

Thanks guys,

I think that's what we'll do:
get a PCI e 2.0 HD 5670 plus upgrade to 4GB - everything else will call for a newer board
