Ok you say so what.. well I was thinking it would be good to upgrade to a series 8 graphics card so out I went with cash in my pocket and purchased a series 8 gamers graphic card … it will improve your game play … Wow I need that Ok.
3D .. GeForce 8 Series get it in there latest drivers loaded away we go widows Vista likes it gives it all a 5.4 rating … HHmmm Silent Hunter 3 here we come.
Something wrong here it looks crap and it isn’t running smooth lets change the settings of the Graphics card NNooo its no better back out you come . Back to the shop I want the same make as my 7 series card please HOW MUCH Plonk .
After picking myself off the floor im on my way back home with a inno3D 8500GT 1gb DDr2 PCI-e Graphics card yes lets kick some ass .. Blah Blah .. Silent Hunter 3 hey all looks good lets go up to the Bridge .. Ok lets not … Why because the crew movements are jerky the water splashing over the bow is also and the game looks like its stuttering … F*^”£!” Dam F*^”! so now its back to the inno 7 series graphics card … so don’t think the new stuff is better and/or will work better than what you already have
