LAN Card Name changed after reformatting OS

Hi. I just reformatted my new pc due to many trojans, viruses, registry problems, etc. I got this Windows XP SP3 from my dad and installed it. After which I downloaded different drivers for my main board that is a 865GDMP Pentium 4 3.2. But just lately, I noticed that my LAN controller name had been changed compared to the previous one. But still is functioning good. Can't remember the old Lan name. But for sure its not a "Via Rhine". Is this okay? Will this have an effect on the performance? Should I install and download from the net?
