After major issues over the last year or so trying to play FO3 GOTY on a top of the line quad core, win 7 64 bit machine, i have decided the only way to fix this is to buy or build an outdated, older computer to play FO3 on. I have tried every fix in the book, every patch, every .ini fix, every compatibility setting, everything including reverting back to vanilla to no avil. I have gotten maybe 1 hour into the game ever..... I am done trying to fix this on my current machine. If anyone out there has a recommendation on a build that will run it at the highest settings i am all ears. Couple of questions i have. (only one really) Should i stick with a single core CPU? Possibly a socket 775? I am an Intel man, i am not interested in an AMD CPU. I currently have a older Radeon 5450 64 bit graphics card taken out of an older XP machine that i was told ran FO3 back in the day but would rather step it up a notch to the 256 bit, 1GB Radeon 6870 sitting around not being used atm. I plan on win xp, 32 bit OS, 4 GB DDR2 memory, and a 120 GB SSD. I am not a pro computer builder by any means, but do have experience building a few systems in the past for my personal use. (including this i5 machine i currently use for Skyrim. (and it runs flawlessly.) On a final note, i want to be able to run it at the highest possible settings with a single 256 bit graphics card. (Radeon 6870, Currently running a 6950 on the i5) Any recommendations are appreciated. Thank you in advance for your time :)
