Alright, so I recently "upgraded" my graphics card from an EVGA Geforce GTS 250 to a PNY Geforce GT 520 and my FPS is significantly lower than what it was with the 250. On World of Warcraft the 250 was at anywhere from 45-60 FPS, with the 520 it's anywhere from 10-25. All minimum requirements are met. The computer is an ASUS 5270, about 2 years old and the specifications are as follows: ASUS VH232H widescreen monitor Intel Core 2 Quad CPU Q8300 @2.50MHz (Is that better than Intel Pentium 4?) 8 GB RAM Windows 7 64 bit Home Premium And on a side note, I've been getting simultaneous audio & video stuttering with both graphics cards, and my sound is built in to the motherboard. Could the motherboard be the cause of all of this?
