To the OP, if you're looking for a direct replacement, your old card is a 35W card based on the Caicos chip; the "new" version of that card is the Radeon R5 230, which is based around the Caicos XT, and is again a 35W part. I presume you're not planning to do any gaming with the card?
Im not using for gaming, because my customer have request graphic card Dell OptiPlex 3020 MT. I want find other similar for (AMD Radeon™ HD 8490, 1GB DDR3, FH, 1 DP 1 DVI, (MT))
Any - they are about the same. Here's some -http://www.pcper.com/reviews/Graphics-Cards/NVIDIA-GeForce-GTX-750-Ti-Roundup-EVGA-Galaxy-and-PNY-Overclocked
If I don't look at reviews, for gtx, I tend towards Asus.
