Packet Loss with Suse 9.1 and Win XP

Hi guys, I've recently bought a new PC using a ASROCK P4VT8 motherboard 512MB Ram, SATA HD and a couple of cheep network cards (yes I understand this is probably my downfall)

I installed SUSE 9.1 on to it and plugged it into my switch i then assigned an IP address and tried setting up Samba on the linux box....
This all went fine until a few hours later when I was playing some music from my linux box on the win XP box and it dropped out quite considerably a few times...

So then I tried pinging my win xp box and visa versa and noticed loads of lost packets (between 10% and 50%) bizarrely enough though if i flood ping the machine i dont drop any packets.
I tried changing network cables but no use, I had a problem before with confilicting IRQ's so I tried swapping my card around some of the ports(as my bios wont let me alter IRQ allocation) but still no good. I disabled everything in the bios apart from onboard IDE and it was still dropping packets.

Ifconfig does report none dropped though:
eth1 Link encap:Ethernet HWaddr 00:40:F4:7E:4B:80
inet addr: Bcast: Mask:
inet6 addr: fe80::240:f4ff:fe7e:4b80/64 Scope:Link
RX packets:28228 errors:0 dropped:0 overruns:0 frame:0
TX packets:33986 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:2965622 (2.8 Mb) TX bytes:19962383 (19.0 Mb)
Interrupt:11 Base address:0x7b00

I then tried pinging my ISP's server through my other networkcard and it didn't drop any packets so i thought this one may not have an IRQ problem, so I changed my settings in YAST to use eth0 as the internal network card and it started dropping packets on that card...
I then checked my windows XP settings and the network card reports no conflicts there either
So im at a bit of a loose end as to what the problem is??

Any ideas would be much appreciated,
