i have an old pc with:
CPU: Intel P4 Northwood @2,53 GHz
RAM: 2 GB DDR @300MHz
Motherboard: ASUS P4P8X with AGP 8x
OS: Win XP pro SP3/Win 7 pro SP1
OLD GPU: Sapphire HD 3450 (512MB DDR2)
with the HD 3450 i was able to play games like Unreal Tournament 3 at 1024x768, medium settings at 45-50 fps (sometimes 55-60). yesterday it stopped to work.
i need a new gpu with similar (or higher) specs.. my budget is 75$, max 90...
what could i take?
