I'm currently on the market for a laptop computer because my wife wants me to get rid of my XPS 410 desktop to make room in our guest room. I upgraded my XPS 410s graphics card with a Geforce 8800GTS and I was wondering if I'd be 'downgrading' in graphic performance with a Geforce 555m GT. Thank you in advance for your response(s)!
Because it'll be a notebook - not a desktop - it will be at best even in performance - likely lower. Notebooks just don't make good gaming platforms - period.
NVIDIA GeForce GT 555M - Notebookcheck.net Tech
The NVIDIA GeForce GT 555M is a fast middle class graphics card for laptops. It is on the GF108 and GF106 chips with different shader counts, clock speeds and memory configurations. It stems from the Fermi generation and supports DirectX 11 and OpenGL 4.0.
Versions (ordered by performance)
The GeForce GT 555M's graphics performance should satisfy most users. It can't quite reach the rival model from AMD, the Radeon HD 6850M (5232 points, Acer Aspire 7750G) with 4999 points, but in return, the very popular GeForce GT 540M is surpassed by 41% (3551 points, Schenker XMG A501). Now we'll take a look at the 3DMark 11 (1280x720) GPU score, where the GeForce GT 555M clearly places itself in front of the GT 540M (897 points) with 1146 points. At the same time is positions itself behind the Radeon HD 6850M (1480 points). Unigine Heaven 2.1 Benchmark (1280x1024, high, normal tessellation) opposingly favors the Nvidia graphics card. While the GeForce GT 540M reaches 13.3 fps and the Radeon 6850M reaches 14.9 fps, the GeForce GT 555M achieves 17.3 fps.
Bear in mind that it's not solely video alone that determines performance - and by every measure from chipset to RAM to hard drive, a notebook is slower than a desktop.
