I want to upgrade my graphics card on my desktop from an OEM NVIDIA GT 520 1GB GDDR3 to an XFX Radeon HD 6870 1GB GDDR5.
My other specs:
- Intel Core i5-2320 @ 3GHz
- 6GB 1333MHz RAM
- 1TB 5400RPM HDD + 500GB external USB HDD
- 300W PSU (which I know I'll have to replace if I get a new graphics card)
Will I notice a significant improvement in performance when gaming if I swap out my GT 520 for an HD 6870? How much of an improvement will it be? Can you guys give specific FPS improvements if possible? Is the performance improvement worth spending $165 (Canadian dollars) for an XFX Radeon HD 6870 and another $60-$70 for a new power supply?
