So my only option is to use the integrated intel gfx?

Annoying, but this happens so rarely I am not very concerned at this time.

As long as the intel wireless works, I am not very concerned about this.

My other option for roughly the same price is

ThinkPad T530

Processor:	Intel Core i7-3520M Processor (4M Cache, up to 3.60 GHz)
Display Type:	15.6" HD+ (1600 x 900) LED Backlit AntiGlare Display,
Mobile Broadband Ready
System Graphics:	Intel HD Graphics 4000
Total Memory:	4 GB DDR3 - 1600MHz (1 DIMM)       [ I'd likely need to
upgrade this separately ]
Pointing Device:	UltraNav with Fingerprint Reader for Color Sensor,
Smart Card Reader
Camera:	720p HD Camera with Microphone
Hard Drive:	500GB Hard Disk Drive, 7200rpm
Optical Device:	DVD Recordable 8x Max, Dual Layer, Ultrabay Enhanced
System Expansion Slots:	Express Card Slot & 4-in-1 Card Reader & Smart
Card Reader
Battery:	6 Cell Li-Ion TWL 70+
Power Cord:	90W AC Adapter - US (2pin)
Bluetooth:	Bluetooth 4.0 with Antenna
Integrated WiFi Wireless LAN Adapters:	Intel Centrino Advanced-N 6205 AGN


I really need to make my decision today.  I need a development laptop
to replace my desktop.  Graphics don't need to be great but should be
non-VESA
