I'm looking to upgrade my machine for primarily to run Quake 4 and Doom 3 better.
My system specs are:
2.26 Ghz Pentium 4 Northwood 512kb L2 cache
Gigabyte Titan 8iHXP rev 2.1 motherboard with latest Bios
2 x 256 megs PC1066 RDRAM
MSI Geforce 6600 GT 128 meg AGP
Soundblaster Audigy Gamer
Windows XP SP2
drivers all latest version
I can make three different upgrades for about 200-ish dollars.
I could get one of the following:
3.06 GHZ P4 with hyper-threading (and my motherboard does support HT I've already checked.)
XFX Geforce 6800GT 256 meg AGP
512 more megs of PC 1066 RDRAM
I'm leaning towards either the CPU or the graphics card, because I've increased the RAM to one gig by temporarily borrowing someone else's ram, and I didn't notice much difference, Doom3 still runs at medium quality. And I think my 6600gt is CPU limited.
The 6600GT is nice except that it wants to run medium detail on everything and I was under the impression that it would do high detail when I bought it a few months ago.
