Now that you told me a single core processor should work, tell me if these specs will even make the game playable. I already know it will be on low setting. Funny story I should mention, when GTA3 came out, I played it on an eMachine that had an 800mhz Celeron, 64mb RAM, and a 6MB integrated graphics card. If I could play a game like that, I could tolerate any game on Low settings, lol.
Here are my current computer specs. Can I at least play GTA4 on low with this:
Athlon XP 3000+ (Around 2.1 ghz I believe)
1GB RAM
MSI 6600GT (I think it has 128mb RAM)
Windows XP Home
And updating right now isn't really an option. So I have to make do with what I have right now and if it isn't enough then so be it.
