My Dell Dimension 9200 has had a nVidia Geforce 8600 GTS since I bought it from DELL just over 4 years ago and the graphics card has completely died recently and I'm running on a borrowed ATI card for the time being so the questions are ...
(1) There are many better replacements for the GTS 8600 but how do I select the right one ?
(2) I found the GTS 450 which seems to fit the PC in terms of PCI Express, Memory Interface etc etc BUT how do know that the PC power supply will handle the new GP ??
The GTS 450 will plug into the motherboard ok (2 slots wide) and has an additional 6 pin plug for additional power cable which was used on the older 8600 GTS, and has more memory and faster processing power.
Any help , pointers or advice would be very useful before I hand out the dosh (£)
The 5770 cards want a 450W PSU, and the 450 GTS wants a 400W PSU. I put a 450 GTS in my dell XPS 400, upgrading from a 6800. I also had a 375W PSU, but after Best Buy warned my dad of the new GPU frying my mobo (even though the PSU had plenty of +12V rail voltage), we got a 600W Corsair single rail Gaming power supply. I would encourage you to get a new power supply also, even though I 'think' the power supply could handle the 450.
The multi rail power supplies like the 375W Dell are supposed to have the power draw spread evenly across all the rails. I am not shure how to do that or what happends when that is not done. My single rail Corsair eliminates that problem.
For graphics card power, the ATI 5770 is a better choice for around the same price. I didn't want any Nvidia to ATI issues when upgrading my own card, so I went with the 450. But I may have just been paranoid. I would definitatly recomend getting a new PSU if you got it.
Both the 5770 and 450 would be good upgrades for you graphic power wise. Also there is the Nvidia 460 768MB card around that price.
