My HP P7 1010 is running really slow on alot of games now a days and I need to know if I can get a new graphics card without replacing anything else.

Here are my specs :
Motherboard - N-Alvorix-RS880-uATX (Alvorix)
CPU - AMD Athlon II X4 645
Memory - 6 GB
Video Graphics Card - ATI Radeon 4200
My power supply is 250W

Any help is appreciated!
