I'm looking at upgrading my current video card "ati radeon 4670". Wanna ask what's the best graphics card, economical since i'm on a tight budget. My board is Asus M5A88V-evo with Athlon X3 455 3.3GHz. Thanks!
Nvidia/Ati, it doesn't matter, you are looking for a Pcie card, which is the name of the slot that it fits into, there is no difference between Nvid or Ati in that respect, they both cater for the format
Apart from that detail, the Radeon 7770 is the next level up from the 6770, which replaced the 5770, they aren't Nvidia cards, they are Ati/Radeon cards
and would do just fine in your rig
