Got a new card, cant play BF2 on all high settings. Could this be because my motherboard may not be 4X AGP or because I am only using a 300W PSU?
Any other reason?

To play BF2 on high settings you should have at least 1.5 GB RAM. Trying to run a 7800GS (with 7900GT core as you say) on a 300W PSU may also present a problem (depending on what else you have in your rig). I wouldn't recommend anything less than a good brand 400W PSU with lots of amps on the 12V rail for such a card, and preferably a bit more if your rig is loaded with harddrives and other peripherals.

Thanks guys. Looks like I need to get an 8X agp mobo, an extra 1Gb RAM, a 400W PSU and something better than an Athlon2400. Interesting.
All in good time.
Thanks again.

My full specs;
512Mb RAM
80Gb HDD
Geforce 7800GS (7900GPU) 512Mb
bog standard 300W PSU

Tragic really when written down. Time to upgrade. What would you recommend? Not OTT pricey but by no means cheap.

Not being funny, but why would you spend 300+ on a graphics card to place in that system...
You now need a new motherboard, CPU, memory and PSU. At which point you should go for PCIe which now makes your card redundant.
As for a new system. PCIe based 939 Motherboard + chip which should drop like a stone when Intel release the Conroe chip http://www.dailytech.com/article.aspx?newsid=2800
at least 1 gig of memory.
decent PSU at least 400+watts

although that will make your card useless, but buying another agp based system would make yet another bad choice.

IMO I would send back the 7800GS and just save your money until you can get a better motherboard with PCIe and a A64 939 motherboard plus more memory 512mb of memory is not enough for todays games,and the 300watt powersupply is holding you back too.AMD Athlon 64 3200+ Venice $103 and these overclock to 2.5gig pretty easy and a Epox EP-9NpA7I $65,2gig of Patriot memory for $124 after the $61 mail in rebate.and a OCZ powerStream 520watt for $109 after the $25 mail in rebateand a XFX 7900GT for $234 after a $30 mail in rebate and for $ 635 you would have a great system ,if that is to high then you need at least a better power supply and more memory.

What you need is an Asrock 393 Dual-SATA2 motherboard, coupled with your choice of a 3000+ or 3200+ cpu, some more memory and some form of sound card (the onboard sound is dire unfortunately).


The Asrock board features both an AGP port and a PCI-e 16x slot. The AGP port is "real" and not some horrid PCI mode pretender.

In addition the board features a "future CPU" slot which can be used to upgrade to M2.


This motherboard is cheap, but definitely not nasty (just make sure you flash the latest official BIOS). I use the board myself and sell systems based around it.
