Ive updated my gpu drivers and ever since then my gpu drivers also fail then recover 5 minutes later, this is so annoying when playing games, css run, left4dead seems to crash under 20 mins.. its all source games, also just wen using windows normaly. sometimes the drivers dont start working and i have to reset my pc to use it.. its so annoying, ive tryed rolling back drivers, downgrading drivers but nothing, if anyone knows of a QUICK fix, let me know.
now as for upgrades:
896MB XFX GTX 260 Black 55nm
1GB XFX HD 4870
1GB Sapphire HD 4870 Toxic
1GB XFX HD 4850
1GB Sapphire HD4890 OC
Bear in mind that money is the main issue, i dont need a major performance increase as my 1gb 8800gt was doing it for me..
i have to say im quite taken by the 4850 and the 4870 toxic, but i really cant afford to pay that much atm and i need the gfx asap.
im running 1680x1050 with max aa and af in css.. i need to be able to play cod4 and lotro and other games with dx10.. is the 4850 capable?
